RJ45 connectors between the clock board and the TIB, and the ones of the RJ45 connectors of thelinks between the TIB and the backplanes, are assigned as it is shown in table 7.1. The signal namedas CABLE DETECT, not yet mentioned, is used to ensure that the plug is connected properly andjust consists on a 1 kΩ resistor to ground in the reception side, and an input pin of the FPGA witha weak pull-up in the transmission side. So, the FPGA detects if it is properly connected or not.

Apart from these RJ45 connectors, others will be available in the TIB as spares, or with the aimto be used to implement advanced features like the ones explained in section 7.3. It is important topoint out that the TIB is compatible with two different front-end boards (NECTAr and Dragon),two different clock boards (MUTIN and White Rabbit) and will work in LSTs and MSTs. A lot ofcoordination work has been required to achieve this compatibility.
7.2 Hardware stereo trigger
As was explained in section 3.2.8.1, the hardware stereo trigger function consists of looking forsimultaneous triggers in neighbour telescopes, inside a time window of a few tens of nanoseconds,with the aim to readout only the events which triggered more than one telescope. As the probabilityof having more than one telescope triggered by NSB inside this short time window is rather low, thestereo trigger detects most of the events caused by Cherenkov showers, while rejecting most of theNSB events. The rejected events are never digitized, not contributing to the dead time. Thus, thetelescope readout rate is reduced, so it is possible to reduce the Level 1 thresholds and increase thesensitivity to low energy γ-rays4.
7.2.1 Timing restrictions
In order to look for coincidences inside the mentioned time window (typically 50 ns), the TIB ineach LST camera must receive the Level 1 trigger signals from its neighbour LSTs plus its local Level1 trigger. However, as the neighbour LSTs are far away (at distances of around 100 m), their triggersignals will reach the TIB some time after the local Level 1 trigger. In this way, the local trigger mustbe delayed a time equivalent to the propagation delay before looking for coincidences. The situation
4To optimize the sensitivity to low energy γ-rays, the thresholds must be as low as possible, while maintaining asustainable readout rate.

becomes more complicated if we take into account that each neighbour LSTs can be separated adifferent distance. Moreover, the time of flight of the Cherenkov light is different depending on thepointing direction. At the end, all these delays mean that the data must be stored in the analogmemory buffers until all the triggers from the neighbour LSTs reach the local telescope, the TIBdecides if there has been a coincidence or not and, in the positive case, the camera trigger signalis distributed to all the clusters in the camera. Therefore, the analog memory buffer must be longenough to keep the signal stored until the trigger arrives.
The Dragon front-end boards are equipped with four DRS4 [56] chips with 1024 analog memorycells in each channel, which means that it is able to store up to 4096 ns with a sample frequency of1 GHz. This is required to implement the hardware stereo trigger in the LST subarray, and thusachieving the best sensitivity to low energy γ-rays. In the next subsections the different sources oftime delay are analyzed and how the Dragon front-end board buffer can cope with them.
7.2.1.1 Compensation of the fixed delays
The approximate fixed delays which contribute to the minimum length of the memory buffers,considering optical fibers with a refraction index of 1.5, are the following:
• 220 ns corresponding to Level 0, Level 1 and the distribution through the clusters until reachingthe TIB (break down in table 3.1).
• 500 ns for the 100 m optical fiber between the TIB and the LST basement (see figure 7.5).
• 500 ns if the neighbour LST is placed at 100 m from the local one, or 700 ns if it is 141 maway (see figure 7.6).
• 500 ns for the 100 m optical fiber between the LST basement and the TIB.
• 170 ns for the trigger distribution of the camera trigger signal down to the clusters
This means that all the inputs must wait for the trigger from the furthest telescope, which needsat least 2090 ns to reach the telescope which we are considering as local.
7.2.1.2 Compensation of the Cherenkov light time of flight
The Cherenkov showers are generated at ca. 10 km height, which is far enough to consider thephotons as forming a plane wave front. Thus, if all the telescopes are pointing to the zenith, the wavefront will reach them at the same time and only the fixed delays explained in section 7.2.1.1 needto be taken into account. However, in real operation the telescopes will not be generally pointingto the zenith, but to a certain location defined by specific azimuth and elevation angles. In thisconditions the distance travelled by the photons is not the same for each telescope, and thereforethe shower images will be formed at different times. The delay differences due to the different timeof flight of the Cherenkov photons must be compensated in order to perform the coincidences of theimages caused by the same shower.

As it is easy to understand from picture 7.7, when two telescopes are aligned with the pointingdirection, the different distances travelled by the Cherenkov photons depends on the elevation angleθ as defined by equation 7.1:
∆d = d cos θ (7.1)
However, as the telescopes are not usually aligned with the pointing direction, the additionaldistance at ground level that the Cherenkov photons must travel through (d in equation 7.1) dependson the the azimuth angle ϕ.

Figure 7.8: Different time of flight depending on the azimuth angle
Considering four LSTs placed at the corners of a square, and oriented with respect to the coor-dinate system as shown in figure 7.8, the distance d used in equation 7.1 for telescopes 3 and 4 withrespect to 1 and 2 respectively, are defined by equation 7.2, for ϕ < π/2.
d = l cosϕ (7.2)
On the other hand, the distance d for LSTs 2 and 4 with respect to LSTs 1 and 2, is given byequation 7.3, for ϕ < π.
d = l sinϕ (7.3)
7. Trigger Interface Board. 155
Thus, for θ < π/2 and ϕ < π/2, the different time of flight of the Cherenkov photons coming toLST 3 with respect to LST 1 will be given by equation 7.4, while for LST 4 with respect to LST 3it will be given by 7.5.
∆time of flight31 =l
ccosϕ cos θ (7.4)
∆time of flight43 =l
csinϕ cos θ (7.5)
Similar equations can be obtained in a similar way for any two pair of telescopes. It is easy tosee that the maximum time difference to be compensated in the TIB will be the one required by thephotons to travel a distance equivalent to the maximum telescope separation in ground, i.e. 141 m.In fact, the telescopes will never point at elevation angles lower than 155, so the maximum distancedifference is 136 m, corresponding to 454 ns. This time should be added to the 2090 ns due tofixed delays, so a buffer of at least 2544 ns is required. Moreover, some more time should be addedto perform the logic operations in the TIB, generate the optical pulses, send the different signalsthrough the RJ45 cables in the camera or just as a safety margin. Therefore 3 µs can be consideredas the minimum time difference required6, so the 4096 cells of the Dragon front-end board, operatingat 1 GHz sampling rate, should be enough.
It is worth to mention that in normal operation the IACTs will be tracking the γ-ray sourcesthrough the sky during some time, from several minutes to hours. During this time the azimuthand elevation angles change, and therefore the delay differences to be compensated. Thus, thepointing direction must be updated quite often and the compensation times must be recalculated.As an example, in order to compensate time errors lower than 2 ns, the pointing direction shouldbe updated for every change of 0.34, corresponding to 82 s in the worst case, when the IACTs arepointing near the zenith. The pointing direction is provided by the slow control system.
7.2.1.3 Synchronization with local trigger
The delay adjustments explained in sections 7.2.1.1 and 7.2.1.2 are useful to verify if the Level1 triggers generated in the local LST and its neighbours are happening inside the coincidence win-dow, and thus fulfilling the stereo trigger condition. Due to statistical fluctuations in the showerdevelopment, there is a certain jitter in the arrival times of the Cherenkov photons, which makes theoptimum duration of the coincidence window to be around 50 ns. This effectively means that, forevery single event, the stereo condition can be accomplished at any time during inside the window,with an uncertainty of several tens of nanoseconds. Due to this uncertainty, it is rather inconvenientto generate the camera trigger signal synchronized with the time at which the trigger condition isfulfilled (see figure 7.9). As it was briefly mentioned in the introduction of chapter 3, one of thetargets of the trigger system is to minimize the jitter to reduce the amount of samples required foreach event (and, as a consequence, the dead time) and to allow the calibration of the DRS4 cells.Therefore, a jitter of up to 50 ns in the trigger time is not acceptable.
5For lower angles, the length of the path in the atmosphere which the Cherenkov photons must travel through, isvery long and the telescope response is degraded.

(b) Late trigger condition
Figure 7.9: If the camera trigger signal is synchronized with the trigger condition, the time requiredto generate the trigger command is variable
Nevertheless, the time uncertainty in the compliance with the trigger condition is not a realproblem. In fact, every LST has to read its local data, and these local data are synchronized withthe local trigger, not with the trigger condition. So, the camera trigger signal must be generated afixed and precise time after the local trigger, as shown in figure 7.10, whenever the trigger conditionwas satisfied. This fixed time must be somewhat longer than the longest time required to compensatethe delay differences and to finish the coincidence window.
7.3 Advanced features
Interfacing with the other trigger generating subsystems and implementing the hardware stereotrigger for four LSTs are the two basic functionalities of the trigger interface board. However, thereare other interesting features that can be implemented in the trigger interface board, which aredescribed in this section.

7.3.1 More LSTs
In principle, there will be four LSTs in the CTA array, both in the north and south hemispheres.However, in the future more LSTs could be built if there were a special interest in improving evenmore the sensitivity or reducing the observation time at low energies7. In anticipation of this possibleenlargement, the trigger interface board is able to handle up to nine LSTs and perform the stereotrigger algorithm with all its inputs.

Figure 7.11: 9 LST possible layout
With a layout like the one showed in figure 7.11, the required buffer size needs to be increasedin 700 ns corresponding to the additional 141 m of optical fiber between the most separated LSTs(eq. 7.6), plus 470 ns corresponding to the increment in in the time of flight (eq. 7.7). Thus, thebuffer must be able to store at least 3714 ns of signal, and there would be 382 ns of margin for theTIB logic operations, distribution, etc, considering 4096 memory cells and a sampling frequency of1 GHz.

7The higher the number of LSTs, the larger the number of recorded low energy events and, at the end, the shorterthe time required to obtain statistics and scientific results.

7.3.2 MSTs contributing to the LST stereo trigger
The readout of the MSTs will be based on NECTAr chips8, which only have 1024 memory cells,so it cannot store more than 1024 ns in its buffer if sampling at 1 GHz. This means that the MSTcameras can not wait for the trigger information from the neighbour IACTs, nor be triggered in ahardware stereo mode. However, they can contribute to the stereo trigger algorithms running ontheir LST neighbours, as sketched in figure 7.12. Provided that the distances are short enough, theMSTs can use their trigger interface boards to broadcast their local Level 1 trigger pulses to theirneighbour LSTs, which can wait for them and thus take this information into account in their stereotrigger algorithms. This idea can take advantage from the TIB capability to handle up to 9 triggerinputs, without requiring to build more expensive LSTs. Nevertheless, as the MSTs and LSTs areoptimized for different γ-ray energy ranges, the gain in performance of the LST will be minor.

7.3.3 Slow controllable functionalities
As will be described in section 7.4, the TIB is a flexible system essentially implemented in anFPGA and with a micro-PC used for slow control. This architecture makes possible to implementadditional functionalities in a straightforward way, as well as to control important parameters dy-namically. For instance:
8In fact, only some MSTs will be based on NECTAr, while others will follow different architectures. Anyway, if theTIB would be used in this other MSTs, the situation would be the same.
160 7. Trigger Interface Board.
• The duration of the coincidence window can be changed by the slow control system.
• The trigger condition can be changed, in order to choose to look for coincidences of 2, 3, 4 oreven more telescopes. Disabling the stereo mode and triggering only in mono mode is also anoption.
• The local Level 1 trigger rate, stereo trigger rate and the trigger rates from the neighbours canbe monitored by the slow control system, which can take decisions based on this information(change Level 1 thresholds, change Level 1 trigger region size, change stereo trigger condition,etc.).
• The temperature and the status of the optical links can also be monitored, generating alarmsif a failure is detected.
7.3.4 Busy state
One of the additional functionalities foreseen in the TIB is a busy state, to avoid distributingnew camera trigger signals to the clusters while the readout is still digitizing. This can be requiredif the readout system is not able to discard these triggers by itself, and it would be as simple asignoring all the triggers produced during the dead time started after a trigger command.
This scheme could be more complex if different dead times among clusters are considered. Forinstance, if a scheme like Colibri is used, only the clusters which are effectively read-out would sufferdead time and, as they would start digitizing at slightly different times, their dead times would alsofinish at slightly different times. In this case, a BUSY signal (already considered in section 7.1),obtained as the global OR of the busy state of all the clusters, would be required.
7.3.5 Topologic stereo trigger
The next step to improve the stereo trigger performance and the noise rejection in an stereoscheme consists on using not only the information about when an IACT was triggered but alsowhat part of the camera caused the trigger. This information can be used by the stereo systemto check if the local triggers are compatible with the expected patterns for single γ-ray-like eventsor, on the contrary, they correspond to different events which occurred at the same time just bychance. In the last case, it is very likely that some of these events were caused by NSB, so theyshould be discarded[143]. Figure 7.13 show several examples of stereo trigger patterns compatiblewith Cherenkov showers or not.
The implementation of a topolologic stereo trigger working as described in the previous paragraphis much more complex than the basic functionality, requiring to send to the neighbours not just thetrigger pulse, but also a piece of information containing which cluster was fired, or at least in whichpart of the camera was placed the cluster that was fired. Nevertheless, the optical links betweentelescopes can be used to broadcast this information, and the FPGA firmware can be improved tohandle it, so in principle it is not impossible to implement the topologic stereo scheme with the TIB.An important difficulty would be how to send the number of the local fired cluster to the TIB. Thediscussion about this is still an open issue, and the topologic stereo trigger will be an important lineof work during the next years.

7.4 Technical description
7.4.1 General architecture
The TIB is implemented in a single PCB housed inside a 19” 1U rack box, as shown in figure 7.14.This rack box will be placed inside the camera, connected to the central backplane, the slow controlunit, the clock board, the calibration box, the TIBs in other neighbour IACTs and the power supplyunit, as was described in section 7.1. At the same time, the Trigger Interface Board is composed ofseveral electronic subsystems, most of them handled by an FPGA as it is shown in figure 7.15.
Figure 7.14: Trigger Interface Board prototype inside the 1U rack box
The different subsystems are described in the following subsections.
7.4.2 Optical links
Some essential hardware elements of the Trigger Interface Board are the optical links. Even in thecase of MSTs triggering in mono, where no communication with neighbours would be required, some

optical links are needed for the communication with the calibration box (calibration and pedestaltriggers), or as an alternative possibility to implement fixed delays with optical fibers. The maincomponents of the optical links are described in the following subsections.
7.4.2.1 Optical fibers
Between every two modules connected (TIBs of neighbouring telescopes, calibration boxes, etc.),there will be a cable containing two multimode optical fibers 50/125 OM3 [144] [145]. This kindof optical fibers are suitable for links of up to 550 m length, handling bit rates of up to 10 Gbps,corresponding to pulses as short as 100 ps. As the distance between telescopes will never be longerthan 182 m (supposing an unlikely 9 LST subarray), and the transmitted trigger signals are expectedto be around 5 ns width, this kind of optical fibers are very appropriate for our system. Additionally,as this kind of optical fiber cables are very common in LANs, they are quite cheap, with prices around0.50 AC/m.
The optical fiber cables are terminated with standard LC multimode duplex connectors, like theone shown in figure 7.16.
7.4.2.2 Transceivers
Two options were considered to implement the optical transceivers: Using standard SFP modules,or using discrete VCSELs and PiN photodiodes mounted inside LC housings.
7. Trigger Interface Board. 163
Figure 7.16: Duplex LC connector
7.4.2.2.1 SFP modules
The first option considered for the transceivers was to use a standard SFP module like the AFBR-5715ALZ from Avago Technologies which is shown in figure 7.17(a). These transceivers consist ofa transmitter section based on a 850 nm VCSEL (Vertical Cavity Surface Emitting Laser) and areceiver section containing a PiN photodiode, together with their drivers, amplifiers and other an-cillary electronics [146]. One of the optical fibers in the cable is connected to the transmitter andother to the receiver, in order to build the bidirectional link.
The transceiver mentioned above is suitable for OM3 optical fibers, reaching a maximum datarate of 1.25 Gbps. These means that the shortest pulses will be 0.8 ns wide, still shorter thanthe expected pulses (around 5 ns). Apart from the transmitted and received trigger signals, thetransceivers generate two control electronic signals named TX Fault and LOS to indicate possiblefailures in the transmission or the reception respectively, and receive one signal TX Disable, whichswitches off the transceiver when it is set to high level. Subsection 7.4.4.7 explains how these signalsare handled by the FPGA.
Regarding the mechanics, the transceivers comply with the Small Form Factor Pluggable (SFP)standard. This allows to use housings from different suppliers, like the one shown in figure 7.17(b),able to house up to 4 transceivers inside. When some link is not in use, the transceiver can be pullout from the box, or just never being installed, saving resources.

Figure 7.17: Transceiver and housing for 4 SFP transceivers
Nevertheless, the SFP transceivers have a minor difficulty: the transmitter must be driven byLVPECL signals, and the receiver also provides LVPECL output signals. This logic standard cannot be managed directly by the FPGA, requiring an intermediate stage for translating the LVPECL
164 7. Trigger Interface Board.
signals to LVDS or other standard supported by the FPGA. This translation can be implementedwith the differential translators SN65LVDS100 and SN65LVDS101, from Texas Instruments [147].SN65LVDS100 performs the conversion of the LVPECL signals into LVDS ones, while SN65LVDS101is used in the LVDS to LVPECL translation.
In spite of this inconvenient, the AFBR-5715ALZ SFP transceivers were selected to be mountedin the first TIB prototype due to their simplicity and with the aim to use standard solutions.
7.4.2.2.2 Discrete VCSELs and PiN photodiodes
Due to some problems found during the tests of the first TIB prototype (see section 7.5.9), anad hoc design for the transceivers has also been considered. Designing the optical transmitter andreceiver with discrete VCSELs and PiN photodiodes is an option which provides with great flexibilityto optimize the bandwidth, the cost or the power consumption. The drawback is that some analogprocessing stages need to be designed in order to feed the VCSEL with a signal inside its inputrange, and to recover an LVDS signal from the analog output of the photodiode. The most criticalcharacteristic is the bandwidth, which must be as large as possible in order to have pulses with verysharp edges, thus maintaining the timing information.
The design of the transmitter is shown in figure 7.18. The VCSEL chosen emits at 850 nm andhas 1 GHz bandwidth. It was provided by AFE ltd. [148] who also assembled it in an LC plastichousing. Considering a single-ended input signal between 0 and 3.3 V from the FPGA, the AD8009[149] operational amplifier is used to adjust the voltage range of the signal and to avoid overloadingthe FPGA. The AD8009 is a very fast operational amplifier (5500 V/µs and 1 GHz bandwidth), ableto drive the VCSEL. Finally the pulses are injected through a decoupling capacitor used to separatethe bias.

The design of the receiver is somewhat more complicated. The photodiode chosen was theS5973-01 from Hamamatsu [150], also with 1 GHz bandwidth and assembled into the LC housing byAFE. First the current signal from the photodiode is introduced into a PACTA [95] transimpedanceamplifier. The output of the PACTA is a differential voltage signal, which is converted into single-ended with an AD8009 configured as a substractor (the scheme is similar to the one described insection 4.2). Then the single-ended output is compared with a threshold with an ADCMP604, whichgenerates the LVDS output. All the receiver circuit is shown in figure 7.19
7.4.3 External delays
As it was previously explained in sections 7.2.1.3 and 7.4.4.1, the camera trigger at the output ofthe TIB must be generated a long9 and fixed time after the local Level 1 trigger arrives. This delaymust be as accurate as possible to know in which cells of the analog memory buffer the signal is.These requirements for the Delayed local signal make inadvisble to delay it with the flip-flop chainsdescribed in 7.4.4.2: first because the accuracy with those delay lines can not be better than 2.5 ns,and second because it would be a waste of logic resources for a delay which, in principle, does notneed to be programmable.
Several options have been tested to implement the long asynchronous delay:
• The most obvious way to implement a long delay is to use a long transmission line. Usingan optical link like the ones described in section 7.4.2 and a long optical fiber, it should bepossible to obtain a very accurate fixed delay. However, this solution would be very bulkybecause a reel of around 500 m of optical fiber would be required for each telescope.
• The programmable delay line 3D3428-15 from Data Delay Devices inc. [151] can add delaysof up to 3825 ns in steps of 15 ns, in a single chip.
• The chip DS1123L-200, from Maxim Integrated [152], is able to add a delay of 512 ns in stepsof 2 ns. So, a chain of 8 of this chips connected in cascade, should be able to add up to 4 µs.
The possibility to use external chip delays was studied in depth during the first steps of the TIBdesign. Both delay chips were found to introduce long delays, with a fine precision, high accuracy,low jitter and good stability, according to their data sheets. The 3D3428-15 was preferred, but therewere no stock in Europe for this chip, so a chain of 8 DS1123L-200 was included in the first prototypeof the TIB. Whatever the solution, it must be tested and characterized, specially in which respectsto jitter, as shown in section 7.5.10.
7.4.4 FPGA and firmware
Both the interfacing and the stereo trigger functions consist of properly managing fast digitaltrigger pulses: replicating, delaying, looking for coincidences, counting, etc. These kind of functionsare the typical ones which can be performed by an FPGA, so this technology appeared as the naturaloption to develop the logic of the TIB. As the FPGAs are programmable devices, they do not onlyprovide with a high performance, but also with a great flexibility. Thus, the firmware installed in
9around 3 µs
7. Trigger Interface Board. 167
the FPGA can evolve with the aim of improving or implementing new functionalities as the onescommented in section 7.3.
The FPGA chosen for the TIB was the Xilinx Artix-7 X7A100T-3FGG676 (figure 7.20, [153])for several reasons:
• It belongs to the newest FPGA Series at the moment of developing the TIB, which meansmore time until it will become obsolete. As the CTA telescopes will have to work during 20years, this is an important point.
• The Artix 7, being the less powerful FPGA family of the 7 Series, is the most suitable for theTIB, which does not require very high computing power. On the other hand, Artix 7 familyis optimized to reduce its power consumption, which is important for all the systems installedin the camera.
• Despite the TIB does not need high computing power, it requires high speed, specially toimplement accurate programmable delays as will be described in subsection 7.4.4.2. Thestandard synchronous logic inside the selected FPGA can work with clock frequencies as highas 500 MHz.
• The selected FPGA has 676 pins, which can be very useful to manage additional interfaces toimplement advanced features.
Figure 7.20: Xilinx Artix-7 FPGA
The firmware running in the FPGA contains several logic modules implemented in VHDL. Thecode can be consulted in [154], but in the following subsections a high level description of the mostimportant modules is presented.
7.4.4.1 High level architecture
Figure 7.21 shows a general scheme of the firmware modules implemented in the FPGA. Somefunctions are programmed directly using libraries provided by Xilinx [155]. For instance, the localLevel 1 trigger input is replicated to be sent to the neighbours by using the FPGA input and outputbuffers. In a similar way, the internal clock frequencies (4 KHz, 50 MHz, 100 MHz and 400 MHz)are obtained from the external 10 MHz input clock by means of the internal PLLs [156], properly

configured with the Xilinx Core Generator [157] and one simple frequency divider. Neverthelessmost of the specific functions of the TIB require the development of specific firmware modules.

The stereo logic involves 3 logic modules. First, the local Level 1 trigger input from the centralbackplane and the inputs from the neighbour telescopes (up to 8) are delayed a programmable num-ber of clock cycles to compensate the delays due to the cable lengths and the pointing direction,as was mentioned in section 7.2.1. The 9 delayed signals are then connected to 9 programmablestretchers, which extend the duration of the trigger pulses until making them as wide as the coin-cidence window. Then, the delayed and stretched trigger inputs are sent to the stereo logic modulewhich has a counter which is able to provide the number of active inputs for every rising edge ofthe 400 MHz clock. If the count is greater than a programmable trigger condition, a stereo triggerwill be generated. However, to be consistent with what was explained in section 7.2.1.3, the cameratrigger pulse is not generated just when the condition is accomplished but it is synchronized with adelayed copy of the local input named “Delayed local” in figure 7.21.
Once the stereo trigger is generated in the stereo logic module, it is sent to the collector, whichis essentially an OR gate that generates a trigger output when the stereo trigger or other input isactive. Depending on the input that caused the trigger output, the collector module generates thecorresponding trigger type which is sent to the central backplane and to the clock board as describedin section 7.1.1. With the aim of being also able to work only with local triggers in mono mode,or to disable the different trigger inputs, the collector also receives a mask to enable/disable eachinput.
The delay for each input, the coincidence window, the trigger condition and other parametersare configured by the slow control module, which receives these parameters from the RaspberryPi through an SPI link. Additionally, the trigger inputs and the trigger output are sent to a setof counters which monitor the trigger rates. These rates can be read by the slow control module,
7. Trigger Interface Board. 169
providing with valuable feedback to select the thresholds, choose a suitable trigger condition or todetect failures. Finally, the slow control module is also able to monitor and control the status ofthe optical links, to configure the external delay and to monitor also the temperature from a chipthermometer.
The following subsections explain some technical details of the most complex modules:
7.4.4.2 Programmable delay lines
The programmable delay lines used to delay each input a different amount of time, are basedon chains of flip-flops as the one shown in figure 7.22. With every clock cycle, the signal presentat the input of each flip-flop passes to the output. So an input pulse requires as many clock cyclesas flip-flops in the chain to go through all the flip-flops and reach the output. This means that,with this structure, the amount of delay is as accurate as one clock cycle, so high clock frequenciesare required to get a fine delay tuning. A clock frequency of 400 MHz was chosen, obtaining aresolution of 2.5 ns in the delay adjustment. Additionally, the input pulses do not reach the outputexactly after N · Tclk ns, but introducing certain jitter. This jitter results from the fact that theflip-flop outputs can only be updated synchronously with the clock leading edge, while the inputpulses can happen at any time. Thus, the input pulse will reach the output of the first flip-flop afteran unknown amount of time between 0 and 2.5 ns depending on the arrival time of the input pulsewith respect to the rising edge of the clock. Nevertheless, as the delayed outputs from the delay linesare only used to check for coincidences inside a time window of several tens of nanoseconds, and thecamera trigger output is synchronized with the local Level 1 trigger, an uncertainty lower than 2.5ns is not very harmful for the trigger performance. It is also worth to mention that the input pulseswill never be narrower than 2.5 ns, so they will always be captured by at least one leading edge ofthe clock.

Figure 7.22: Delay line implemented with a chain of flip-flops
The delays introduced by the delay lines can be as long as 4000 ns, which means that the chainsshould have at least 1600 flip-flops. The first obvious solution to be able to select every possibleamount of delay is to connect each flip-flop output to the input of a 1600-input multiplexer. Such amultiplexer does not exist inside the FPGA, so it should be implemented as a multilevel hierarchy of8 and 4-input multiplexers. A complicated structure like that is not a good solution from a timingpoint of view, because the output signal from the selected flip-flop would have to go through manymultiplexers in cascade and reach its destination in a single clock cycle. So in order to avoid the1600-input multiplexer, a logarithmic structure like the one shown in figure 7.23 was designed.
The amount of delay which should be added by the delay line is configured by the slow controlmodule by means of a 12 bits word. So, every bit set to “1” introduces a delay correspondent to 2p
clock cycles, being p the position of the bit in the 12 bits word. If the flip-flops in the chain are set

in subchains of powers of 2 units as shown in figure 7.23 and the bits of the control word are used toconnect these subchains to the signal path or to bypass them, the output of the chain provides withthe desired delayed output, just with 11 2-inputs switches. Only 11 from the 12 bits of the delayword are used, providing with an adjustment capability of up to 2048 clock cycles (i.e. 5120 ns at400 MHz). Moreover, as the longest delays can only be applied to the local input (the inputs fromthe neighbours have an inherent delay due to the travel through the optical fibers), the delay linesused in the neighbour inputs only use 10 bits and comprise 1024 flip-flops instead of 2048, savinglogic resources.
7.4.4.3 Stretchers
The stretchers are used to make the pulses coming from the delay lines as wide as the coincidencewindow. The duration of the coincidence window is programmable by means of a 6 bit numberconfigured by the slow control module, which expresses the duration in clock cycles. The stretchersuse the same 400 MHz clock used for the delay lines, so the finest resolution is limited to 2.5 ns. Infact, the stretchers use a delay line like the ones described in section 7.4.4.2 to produce the stretching,but with 6 bits instead of 10 or 11. A copy of the input pulses is sent to the input of this delay line,obtaining at the output a delayed signal. Both the delayed signal and the original input feed thestate machine shown in figure 7.24.
State 0Output = 0
State 1Output = 1
Input = 1
Input = 0 & Delayed = 1
Figure 7.24: Diagram of the state machine running in the stretcher modules
After the FPGA reset, the state is 0, as well as the output of the stretcher. When the inputchanges to “1”, the state machine changes to State 1, and the output changes immediately to “1”.This situation remains until the delayed input coming from the delay line changes to “1” and onlyif the non-delayed input has already changed to “0”. This means that:
• If the input is narrower than the coincidence window (as usually expected), the output pulsewidth is the coincidence window duration.
• If the input is wider than the coincidence window, the output width is similar to the inputwidth.
7. Trigger Interface Board. 171
If the input pulses arrive at the stretchers separated by less than the coincidence window width,this scheme does not work properly, so that the system can consider several close input triggers as asingle one, or to produce outputs shorter than the coincidence window. This situation would meanthat a high pulse rate is present at the output of the stretchers, which will be detected by the ITRcounters (see section 7.4.4.6), which in turn will be read by the slow control system, which will takethe appropriate measures.
7.4.4.4 Stereo Logic
The delayed and stretched inputs from the local and the neighbour telescopes are sent to theStereo Logic module, which generates a stereo output if the trigger condition is accomplished. Thetrigger condition consists of having coincident triggers in the local telescope and in one or moreneighbours during the coincidence window. This is implemented by connecting the inputs to a fastcounter which provides, with every leading edge of the 400 MHz clock, the number of inputs whichare set to “1”. The result of the counter is expressed as a 4 bits number, which is compared with thenumber of coincident triggers required to satisfy the trigger condition. The trigger condition can bereconfigured in a very simple way, just modifying this number by slow control. If, besides satisfyingthe required number of coincidences, one of the coincident inputs is the local one, the signal named“Stereo trigger” in figure 7.25 is generated.

Figure 7.25: Stereo logic block diagram
However, as was previously said in subsections 7.4.4.1 and 7.2.1.3, the Stereo Output cannot besimply generated when the stereo trigger condition is accomplished. Instead, it must be generated afixed time after the local trigger, i.e. synchronized with the signal named “Delayed local” in figures7.21 and 7.25. To do this, the Stereo trigger signal is sent to a programmable delay line as the onesdescribed in section 7.4.4.2 and, once delayed it feeds a state machine which generates an “Armed”output. When this Armed signal is set to “1”, a stereo output is generated when Delayed localappears.
The delay line is required to set Armed = 1 only some tens of nanoseconds before the expectedarrival of Delayed local. Of course it is impossible to know accurately when the stereo triggercondition is going to be accomplished and therefore when Armed is going to be set to one (it canhappen at any time inside the coincidence window). However, what it is possible is to know howmuch time the local trigger is being delayed in the Programmable Delay Lines module to compensatethe neighbour’s delays before checking for coincidences and how much delay is introduced in theDelayed local path. Thus, introducing an additional delay of Tstereotrigger ns, calculated accordingto equation 7.8, it is possible to ensure that Armed will be set to “1” between Tcoincidencewindow +Tsecuritymargin ns and Tsecuritymargin ns before the arrival of Delayed local.
172 7. Trigger Interface Board.
Tstereotrigger = Tdelayedlocal − Tcoincidences − Tcoincidencewindow − Tsecuritymargin (7.8)
Figure 7.26 illustrates this calculation. If Stereo trigger is not delayed, Armed could be activateda long time before the arrival of the corresponding Delayed local pulse and this could cause theacceptance of previous local triggers which did not comply with the coincident condition as stereoones. On the contrary, if Armed is set to “1” just a few nanoseconds before the time at whichDelayed local is expected, is very unlikely that a local trigger different from the one which causedthe coincidence could be accepted.

Figure 7.27: State machine which controls the generation of the Armed signal
Regarding the state machine which controls the activation of the Armed signal, its scheme isshown in figure 7.27. It is more complicated than just setting Armed to “1” when Delayed stereo triggerarrives, with the aim to produce only one stereo trigger when the trigger condition is accom-plished during a long time. Thus, starting from the waiting state, it changes to armed whendelayed stereo trigger appears. Then, when Delayed local arrives and generates the Stereo Out-put the state changes to shooted, setting Armed to “0”. In this state, Delayed stereo trigger mustbe “0” to make the state machine go back to waiting state and then being ready to get armed again.
7. Trigger Interface Board. 173
So, if the trigger condition is fulfilled during a long time, the state machine remains in shooted state,avoiding several triggers to be generated for a single long event.
7.4.4.5 Collector
The Collector module implements the interfacing function with the different trigger origins,generating the trigger output signal every time a trigger comes from any of the inputs. Thus, thetrigger output is implemented in a simple way with a 5 input OR gate and an AND gate, as it isshown in figure 7.28.

Figure 7.28: Trigger output generation in the collector module
The AND gate allows to generate a trigger output directly from the local telescope trigger (Input0 signal), whenever the mono trigger mode is selected, as will be the case in the MSTs. It is importantto notice that, whatever the input, the trigger output is generated in a completely asynchronousway, keeping the timing information in the leading edge of the trigger output and introducing verylow (24ps RMS). For the trigger type generation, the input trigger signals are copied and stretchedin order to work with them synchronously with the state machine of figure 7.29.

When the stretched copy of the trigger output signal changes from “0” to “1”, the 3 bits of thetrigger type corresponding to the effective triggering input are calculated, and then a signal calledTXStart is set to “1”, indicating to the SPI module10 that there are data to transmit. From thismoment, the state machine ignores the possible new triggers, remaining in the transmitting state

until the SPI module finishes transmitting the trigger type. Then, The SPI sets to “1” a signalnamed TXDone, indicating to the collector module that it is ready to accept new transmissions.It is worth to say that the collector state machine works with the 400 MHz clock, evaluating thedifferent variables every 2.5 ns, while the SPI module receives a 50 MHz clock for its state machine,sending the bits at 10 MHz.
7.4.4.6 ITR counters
The Individual Telescope Rate (ITR) counters are a set of counters in charge of counting thenumber of input triggers from each telescope (local and neighbours), as well as output triggers,during a certain period of time, with the aim to provide the slow control module with informationto calculate the trigger rates. The trigger rate monitoring is very important to set the Level 1thresholds and the trigger condition to the lowest possible levels, while maintaining the trigger ratebelow the maximum telescope readout rate11.
The design of digital counters entails a compromise between the number of bits of the counterand the maximum counting speed. As it has been represented in figure 7.30, the counter is composedby a chain of 2 bit adders. The time between one addition and the next one must be long enough toallow a carry bit to ripple through the whole chain of full adders and to have the result ready at theinput of the counters to start the next addition. Thus, the more bits in the counter, the longer thetime required to propagate the carries and the lower the maximum frequency at which the countercan work12.

Figure 7.30: Structure of an 8 bit ripple-carry counter
In the particular case of the ITR counters, the inputs will be separated by some µs during normaloperation (i.e. the expected trigger rates are below 1 MHz). If the counters are fed with the inputpulses after going through the stretchers, the pulses to be counted will be long enough to allowthe counters to work at lower frequencies, and therefore to reach higher ranges. The coincidencewindow, and the correspondent pulse width of the stretched pulses will be around 50 ns, but it isprogrammable so, in order to have some safety margin, a minimum pulse width of 10 ns has beenconsidered. Assuming this condition, the counters have been designed to have 8 bits and beingupdated at 100 MHz. Every 10 ns each counter checks if its input has changed from “‘0” to “1”. Ifso, they increment the account, otherwise they do nothing.
In principle, the counters are read-out and reset to 0 every 250 µs (4 kHz rate), so they are usefulto monitor rates between 4 kHz and around 1 MHz. If the rate is higher, the counters maintain their

maximum value (28 − 1 = 255), so the slow control module will know that the rate is too high andit will take the appropriate actions. If it were required to measure higher or lower trigger rates, itwould be possible to do it just by changing the frequency at which the counters are read and reset.
7.4.4.7 SFP control
The optical links used to send and receive triggers to/from the neighbours, as well as the cali-bration and pedestal signals, are implemented in the first TIB prototype by means of TX/RX SFPmodules [146], which provide with several bits to monitor and control the link status:
• TX Disable: When the FPGA sets this bit to “1”, the optical transmitter is switched off.
• TX Fault: If a laser fault happen, the SFP module sets TX Fault to “1”, and disables thelaser.
• RX LOS: A Loss of Signal (LOS) bit indicates that the received optical power is too lowto recover the signal, due to a disconnected or broken fiber, switched off transmitter or otherreason.
The SFP control module simply gathers all these bits from all the SFP modules, forming wordswhich can be read by the slow control module. Additionally, it generates a generic alarm signaldirectly connected to the Raspberry Pi if any of the control bits is indicating a failure. In this way,the slow control module does not need to read the SFP status periodically, but only when a problemis detected.
7.4.4.8 External delay control
In the first TIB prototype, the external delays described in section 7.4.3 are implemented with achain of Maxim DS1123LE-200 [152] programmable delay chips. These chips need to be configuredby sending an 8-bits word to each chip through an SPI link. All the chips share the clock, MISOand MOSI lines, while they have independent chip selects. With the aim to handle these links andsend the configuration information properly, a firmware module was implemented. This modulereceives from the slow control nine 8-bit words (one for each chip) and a signal indicating whenthe configuration of all the chips must be updated (Write ex dels). When the updating commandarrives, the module sends the 8-bit word to one chip after the other until programming all of them.Figure 7.31 shows the state machine of the firmware module.
The process of updating the configuration uses a variable n to select each chip. Thus, when com-ing from Waiting state, the chip corresponding to n=0 is updated in the Writing state (TX start=1starts the SPI communication). Then, when that message has been sent, TX done changes to “1”and the state changes to Handshaking. This state increments n and in the next step the state changesto Writing again to send the configuration message to the next chip. The process is repeated untilprogramming all the delay chips. Then the state comes back to Waiting.
With the aim to initialize all the chips with a known value after the reset of the system, the stateis set to Writing instead of Waiting, so the initial values are loaded.

7.4.4.9 Thermometer
The trigger interface board is equipped with a TC77 [158] chip thermometer, readable by a SPIinterface. The thermometer firmware module is in charge of controlling this SPI interface, readingthe temperature every 250 µs and writing the data in a register accessible by the slow control module.
7.4.4.10 Slow control module
The Slow Control firmware module implements an slave SPI interface which allows the RaspberryPi to read and write 32 bit words. These words are composed of an 8-bit prefix which defines whatinformation is being read or written and 24 data bits. Table 7.2 contains the different codes and thedata corresponding to each one.

Table 7.2: Slow control registers
When an SPI message is received and its prefix does not correspond to a defined one, the slowcontrol module sets an alarm line directly connected to the Raspberry Pi to “1”, and writes theunknown received prefix in the 0xF0 address. In this way, the Raspberry Pi can read what wasreceived, which can be useful for debugging.
Another useful function of the slow control module is to write the initial values of the differentparameters, before receiving them from the Raspberry Pi. This allows to test the different func-tionalities, even without the Raspberry Pi (see section 7.4.5.2). With the aim to have the updatedinformation about the slow control always accessible, a wiki page has been created [159].
7.4.5 Raspberry Pi
The TIB contains a Raspberry Pi micro-computer (figure 7.32), which is in charge of the FPGAconfiguration during the booting of the system and the slow control communication. In spite ofits small size and very low price13, the Raspberry Pi is a complete PC running a Linux operating

system14 which is stored in an SD card used as hard disk [160]. It has several buses: two USBs, oneRJ45, several general purpose pins, one audio connector and even an HDMI. In the case of the TIB,the Ethernet interface will be used to communicate with the camera slow control system, while theGeneral Purpose Input/Output (GPIO) pins are used to interface with the FPGA.
Figure 7.32: Photograph of a Raspberry Pi micro-computer
7.4.5.1 Interface with the FPGA
The Raspberry Pi have 26 pins in its GPIO interface, assigned to different signals as shown intable 7.3.
The signals can be divided in several groups:
• SPI MOSI, SPI MISO, SPI clock, SPI Chip Select 0 (CS0) and SPI Chip Select 1 (CS1)constitute an SPI interface able to control two SPI devices. In fact, all the lines are connectedto the FPGA: CS0 is active during the transmission of the FPGA configuration file in theinitialization (see section 7.4.5.2), while CS1 is used during the transmission of the slow controlparameters. In both cases the Raspberry Pi is the master, while the FPGA is the slave device,which means that the clock is generated by the micro PC.
• I2C serial data (SDA) and I2C clock implement an I2C standard link connected to the FPGA.This interface is not currently used, but the lines are reserved for future uses.
• UART TX and UART RX can be used to implement a serial communication interface betweenthe Raspberry Pi and the FPGA. As in the case of I2C, it is not currently used but reservedfor future uses.

7.4.5.2 FPGA-initialization
The Xilinx Artix 7 FPGAs can be configured in different ways. Taking advantage of the presenceof the Raspberry Pi, the so called “slave serial mode” has been chosen [163]. According to thisconfiguration scheme, the Raspberry Pi sends the firmware to the FPGA during the initializationby means of an SPI interface. Figure 7.33 shows the connections between the Raspberry Pi (labeledas Microprocessor or CPLD), the FPGA and the JTAG connector. CCLK, DIN and PROGRAM Bcorrespond to the 3 typical SPI lines, clock, data and chip select respectively. The Raspberry Piplays the role of master in this communication, generating the clock.
The JTAG connector provides with an alternative and effective way to load the firmware in theFPGA and run tests. In the first prototypes of the TIB an external JTAG connector is present inthe front of the box with the aim to debug problems. In the final Trigger Interface Boards it will bean internal connector.
7.4.5.3 Interface with the slow control unit
The Raspberry Pi is in charge of communicating with the central camera slow control unit, usingthe Ethernet camera network. This interface requires coordination with several CTA teams working
180 7. Trigger Interface Board.
Figure 7.33: Slave serial mode FPGA configuration scheme [163]
on this issue and it was still under definition by the time this thesis was written. However, someguidelines have been given to develop the slow control software. The most important decision hasbeen to use OPC-Unified Architecture [164] as the base communication architecture. OPC-UA worksefficiently to control different parts, whether they are simple or complex, and is multiplattform,offering different APIs for software development. The Raspberry Pi will run an OPC-UA serverimplementation for the Java virtual machine.
7.4.5.4 Other functions in the Raspberry Pi
Apart from interfacing the FPGA and the camera slow control system, the computing power ofthe Raspberry Pi is very useful to perform certain functions and calculations locally, reducing theworkload of the camera slow control. Some of these additional functionalities are:
• Calculation of the number of clock cycles that every trigger input must be delayed, depending
7. Trigger Interface Board. 181
on the pointing direction. The camera slow control can send the pointing direction or directlythe delay in ns, and the Raspberry Pi calculates the delays in clock cycles.
• Centralization of the alarms. The Raspberry Pi checks periodically the trigger rates, the statusof the optical links and the temperature, warning the central slow control only if necessary.
• SSH accessibility, useful for debugging.
7.4.6 Power supply
The Trigger Interface Board receives a single +24 V DC power supply from the camera powersupply system. From this voltage, the power must be provided to the different subsystems, whichrequire different supply voltages. Table 7.4 shows the power consumption requirements of the dif-ferent active hardware elements. In order to satisfy the power requirements efficiently, a two levelspower supply system has been designed, according to the diagram shown in figure 7.34.

Figure 7.34: Block diagram of the TIB power supply system
As the most demanding power supply voltages are the +5 V and the +3.3 V, two switchedDC-DC modules have been used to generate them from the +24 V general supply. This first stepfrom +24 V must be done with switched DC-DCs because the voltage drop is too high to use linearregulators efficiently. On the other hand, the +2.5 V, +1.8 V and + 1 V are generated from +3.3V by means of less noisy linear regulators. The Trigger Interface Board is not very sensitive tothe noise in the power supply because it is a digital design where the most important signals aredifferential, so the switched noise introduced by the DC-DCs is not critical. Nevertheless, the noisein the power supplies has been measured and the results are shown in section 7.5.1.
The different power supply modules have been designed with the Webench Power Designer on-line tool from Texas Instruments [165]. Their schematics, as well as the schematics of all theTIB hardware modules can be seen in appendix A.2. Table 7.5 summarizes the most importantcharacteristics of the designed power supplies.

7.4.7 Temperature monitoring
The Trigger Interface Board includes a TC77 thermometer chip [158], which is read by the FPGAas was explained in subsection 7.4.4.9. Contrary to what it could be expected, the components withthe most restrictive operating temperature range are not the transceivers (which have a VCSEL)but the Raspberry Pi [160], the FPGA [153] and the programmable delay lines DS1123LE [152].Table 7.6 gathers the operating temperature range of the different components, showing an overalltemperature range between 0 and +70 C. The delay line is the most restrictive element, but it isstill not clear if the DS1123L will be present in the final versions of the Trigger Interface Board.
Taking into account the temperature limits from table 7.6 and the temperature measured withthe sensor, it will be possible to operate the camera cooling system [108] between safety margins.
7.4.8 TIB PCB design
The TIB is a complex board which needs to handle many input and output signals, which inmany cases consist of differential pairs. First, there are 24 differential pairs to and from the opticallinks, and other 32 differential pairs connected to the RJ45 connectors. Additionally, there are single-ended lines for the optical links monitoring, 15 lines for the communication with the Raspberry Pi,12 for the control of the external delays implemented with the DS1123L and still some more forthe JTAG interface and the reading of the thermometer. So many lines connected to the 676 padsFPGA, together with the different power supply rails described in section 7.4.6 required a complex16 layer PCB design (figure 7.35) which was developed with Altium Designer [166].
The PCB design considered several restrictions such as the delay equalization of the lines comingfrom the neighbours, the controlled impedance of the differential pairs, the coupling between adjacentlines or the noise from the power supplies. Additionally a 3D model of the board (figure 7.36(b))

7.5 TIB measurements
Two boards of the first prototype of the TIB have been manufactured and tested. The goal ofthis prototype is to test the different functionalities, to improve the FPGA firmware, to develop theslow control software which will run in the Raspberry Pi and finally to provide with a TIB for severalCTA camera integration tests which will take place during 2014. In order to perform the tests, theauxiliary boards shown in figure 7.37 were manufactured.
• Board in figure 7.37(a) simulates the central backplane interface.
• Board in figure 7.37(b) mimics the clock board.
• Board in figure 7.37(c) simulates an optical interface.
• Board in figure 7.37(d) is a generic adapter from RJ45 into SMA connectors.
The first three boards include an MCP2200 chip [167] each one, which can generate input pulsescontrolled by a computer through an USB interface.
The results obtained from these tests and the new requirements requested by the LST and MSTcamera developers will be taken into account for a second, upgraded, version which should be theone finally installed in the LST and MST cameras. The next sections show the main features testedin the TIB.
7.5.1 Power supplies
The first systems to be tested were the power supplies. They work as expected, providing withenough current for the different subsystems. Table 7.7 contains the measured DC voltage levels andthe noise, measured as the AC coupled RMS voltages, corresponding to the different power rails(figure 7.38). The table shows that the measured DC levels are very close to the nominal ones andthe noise power is very low. Looking at the numbers it is possible to notice that the RMS voltagesis higher in the +5 V and +3.3 V power supplies. This is because these two power supplies areswitched ones, in contrast to the others which are generated by means of linear regulators. Theonly problem related with the power supplies is that the +1 V LED indicator does not shine (figure7.38(d)) because it was not selected properly and its threshold voltage is higher than 1 V.

7.5.2 FPGA configuration
The next system to be tested was the FPGA. First it was tested through the JTAG interface,observing that the FPGA was properly installed and the communication was possible. The nextstep was to configure the FPGA with the Raspberry Pi, and this target was also accomplished.
7.5.3 Clock generation in the PLLs
In order to test the different firmware modules running in the FPGA, different frequencies mustbe generated in the PLLs from the original 10 MHz input clock. In the first tests a problem withthe matching of the input clock was found, which made the PLL to consider clock reflections asclock cycles and at the end to generate higher output frequencies than expected. The problem wascaused because the Xilinx core generator does not activate the internal termination of the inputbuffer, represented in figure 7.39. Once the problem was found, it was corrected by activating thetermination explicitly in the VHDL code and the output frequencies were the expected ones.

7.5.4 FPGA delay lines
Once the high clock frequencies were available, it was possible to test the other firmware modules.The next ones were the flip-flop based delay lines described in section 7.4.4.2. In order to test them,
7. Trigger Interface Board. 189
a copy of the input and the output of a delay module were directly connected to two spare RJ45pairs which, after an adapter board like the one shown in figure 7.37(d), were connected to anoscilloscope. Delays from 0 to 1600 cycles (4 µs) were tested, observing a minimum delay of 6.2ns corresponding to 0 cycles, which behaves as an offset added to the configured delay. This offsetis due to propagation inside the TIB, and it does not mean any trouble. Regarding the maximumjitter, it was always limited to around 2.5 ns for all the delays tested, which corresponds to theminimum clock period, just as expected. Figures 7.40 and 7.41 show several delay measurements.
Figure 7.40: 0, 2.5, 12.5, 25 and 30 ns delayed outputs (blue and green) and input (yellow)
7.5.5 Stretchers
The next module to test were the stretchers. As in the case of the delay lines, the output of thestretchers was connected to an spare RJ45 connector in order to measure the width of the pulses.Figure 7.42 contains several measurements showing that the stretcher modules work as expected,i.e. stretching the pulse up to the configured width when the pulse is narrower than the coincidencewindow, and not changing the output width when the input pulse is wider than the coincidencewindow width, as it was described in section 7.4.4.3.

7.5.6 Stereo Logic
The tests of the stereo logic were difficult to perform with the oscilloscope because there aremany signals involved, and not all of them can be represented in the screen at the same time. Theavailable oscilloscope only have 4 channels and the outputs from the RJ45 connectors consist ofdifferential pairs, so only 2 signals could be simultaneously represented without using the memories.Additionally, measuring the signals involved in the stereo logic outside the FPGA adds additionaldelays due to the cables, connectors, etc. which can distort the real situation when looking forcoincidences. In this situation, it was preferred to use a Xilinx tool named ChipScope [168]. Thistool uses the spare resources in the FPGA to implement a virtual logic analyzer, which can beused to see the internal signals, sampling them with an internal existing clock (the 400 MHz onewas chosen), triggering with a selectable signal (the local trigger input was chosen) and storing thesamples in the RAM blocks existing in the FPGA. By means of this powerful tool, all the internalsignals participating in the logic could be represented in a PC like in a logic analyzer. The figures7.43 and 7.44, in the following pages show several typical situations.
Figure 7.43(a) shows a typical situation where a trigger output is generated. The 2nd, 3rdand 4th rows in the figure (inputs< 0 >, inputs< 1 > and inputs< 2 >) correspond to the Level1 trigger signal coming from the backplane and two Level 1 trigger inputs coming from neighbourtelescopes16. These input trigger pulses are delayed and stretched, so 6th, 7th and 8th rows representthe signals coming into the stereo logic module. In real conditions the inputs would show a longerseparation in time and the delays required to compensate them would be longer too. For these tests,short delays have been selected in order to see all the signals which are important for the logic inthe same screen. In this way, the 9th signal (condition) is set to “1” when the trigger conditionis accomplished, which in figure 7.43(a) happens for 3 coincident inputs. The 10th row, namedstereo trigger requires condition to be set to “1” and also checks that one of the active inputs isthe local one. If this is the case, the stereo trigger signal can be delayed, as will be shown in figure7.44(b), or not delayed as shown in figure 7.43(a), generating in any case the 11th signal, labelledas delayed local. This signal changes the state of the state machine shown in figure 7.27, whichis represented by the signal state FSM FFd, changing from waiting to armed, which means that astereo trigger output will be generated when the delayed copy of the local input will arrive. Thisdelayed copy is named as delayed local in figures 7.43 and 7.44. When it arrives, the stereo outputsignal (stereo output) is generated, changing the state from armed to shooted during the triggeroutput duration and, finally changing to waiting again. The last signal, named Stereo T, representsthe trigger output from the FPGA.
Figure 7.43(b) shows the signals in a case in which the trigger condition is not fulfilled becausethere are never 3 coincident signals, and therefore condition is never set to “1”. On the other hand,figure 7.44(a) shows a situation in which the trigger condition requires 2 coincident telescopes, butstereo trigger is shorter than condition because the local trigger is only active during part of thetime. Finally, figure 7.44(b) shows a case in which delayed stereo is delayed with the aim to reducethe time during which armed is enabled, reducing the probability of generating a trigger output dueto a previous non-coincident local Level 1 trigger.

7.5.7 Collector
The collector module inside the FPGA was also tested, obtaining output triggers correspondingto the different trigger inputs. The mask allows to enable or disable the trigger inputs, and thetrigger type is generated correctly. Figure 7.45 shows the output corresponding to a software triggercoming from the clock board. The corresponding code “101” is read in the leading edges of the 10MHz clock. As it was required to represent 3 differential signals with a 4-channel oscilloscope, thetrigger output was stored in memory (blue line) and, using it as trigger, the clock and data lines arerepresented with the yellow and green lines respectively.
Figure 7.45: Trigger output pulse (blue) and trigger type clock (yellow) and data (green).
7.5.8 ITR counters
The ITR counters were also measured, just by setting different input trigger frequencies andreading the accounts, which are updated every 250 µs as it was explained in section 7.4.4.6. Theresults are gathered in table 7.8, showing that the counters work as expected:
As it was expected from their implementation, the ITR counters cannot measure rates with anaccuracy better than 4 kHz (because of the updating period), or to measure rates higher than 1.02MHz, (because they are 8-bit counters). Nevertheless, the current characteristics of the counters aresuitable for the expected rates to be measured in CTA.
7.5.9 Optical links
The optical links were implemented in the first prototype with SFP transceivers, like the onesused in optical Gigabit Ethernet networks [146]. These transceivers are easy to control, and very

adequate for data transmission through cheap OM3 optical fibers in distances of up to 550 m length.However the tests showed that the SFP transceivers were not a suitable option for sending triggerpulses.
When testing an optical link, it was observed a high level of noise in the received signal. Thiswas caused because, in the transmitter, the differential LVPECL inputs are AC coupled as shownin figure 7.46. If the signal is changing very fast, like it is the case in the Ethernet signals17, itworks properly but, this is not the case of the digital trigger pulses. These trigger pulses sent by thecamera telescopes consists of pulses of a few nanoseconds width (around 10 ns), which are sent at amaximum rate of some hundreds of kHz. This means that the baseline is set to “0” during most ofthe time. Looking at the scheme of figure 7.46, it is easy to understand that the DC levels of such adifferential signal are removed by the capacitors, so the DC voltage is the same in the positive andnegative inputs of the receiver (points marked as TD+ and TD- in the figure). In this situation, theslightest noise fluctuations are recognized by the transmitter as “0s” or “1s”, sending noisy pulses.Real pulses are effectively sent, but together with thousands of noise pulses.

The solution to this problem will consist of replacing the SFP transceivers of the first TIB

prototype by analog optical links implemented with discrete VCSELs and PIN photodiodes, as wasdescribed in section 7.4.2.2.2. The transceivers have been implemented in test boards and testedwith two optical fibers of 2 and 500 m. Figure 7.47 shows the measured signals corresponding tothe 2 m link. The purple line was measured with a probe18 with the aim to show that this kind oflinks can handle pulsed signals properly. On the other hand, figure 7.48 shows the input and outputwith a 500 m optical fiber, demonstrating that the optical power and the sensibility of the receptorare adequate. The bandwidth is large enough to allow sharp edges and, as a result, the jitter is verylow: only 77 ps with the 500 m optical fiber.

7.5.10 External delays
The different ways to implement the external delays described in section 7.4.3 have been tested:
7.5.10.1 Delays with DS1123LE-200
The external delays implemented with the Maxim DS1123LE-200 chips [152] were the optionchosen for the first TIB prototype. They were tested and, in fact, used to delay the local trigger
18The length of the probe cable is longer than the one of the cable which connects the LVDS output to the oscilloscope.This is why the LVDS output appears before the analog pulse.
7. Trigger Interface Board. 197
Figure 7.48: Inverted copy of the input signal (magenta) and received LVDS output (yellow) of theanalog optical link, with a 500 m optical fiber
and generate the delayed local signals shown in figures 7.43 and 7.44. Figure 7.49 shows the resultof delaying an input pulse 0, 50, 100, 150 and 200 steps of 2 nanoseconds with only one delay chip,and it can be seen that the delay accuracy is very good and the standard deviation of the jitter isaround 20 ps.
However, when longer delays were implemented with a chain of 8 chips in cascade the resultswere not so good. For a delay of 2.6 µs, a standard deviation of the jitter of 1.4 ns was measured.This jitter is too high, and discards these chips as an option to implement the asynchronous delayof the local input which at the end is used to read the camera, and which should have a jitter lowerthan 1 ns.
7.5.10.2 Delays with 3D3428
In spite of the difficulties with the supply of this chip, it was finally possible to get a sample andtest it. The measurement corresponding to the expected required delay is shown in figure 7.50. Asit can be see in the figure, the jitter is much lower than with the Maxim device: for a 2.7 µs delay,the std. deviation of the jitter is 606 ps. Therefore this chip will be the chosen one for the upcomingversion of the TIB.

Figure 7.49: Input signal (yellow) and delayed 0 (green), 50, 100, 150 and 200 steps of 2 ns (blue)with DS1123LE-200.
7.5.10.3 Delay with an optical fiber reel
The delay can be implemented with a long optical fiber and the analog optical links describedin section 7.4.2.2.2. The measurements shown in figures 7.47 and 7.48 show that this is a feasibleoption. With the 500 m length optical fiber, a delay of 2.53 µs with a jitter of only 77 ps standarddeviation was achieved, which is better than with any existing chip. However, this solution is verybulky and not very feasible to be implemented in an IACT.
7.5.11 Test conclusions
The tests have shown that the first prototype of the TIB can comply with most of the require-ments. Most of the concepts have been successfully tested:
• The stereo trigger and the trigger gathering functions can be implemented in an FPGA, workingat 400 MHz.
• A Raspberry Pi is very useful to configure the FPGA and perform the slow control function-alities, avoiding complex Ethernet implementations.
• The delay lines and the stretchers based in flip-flop chains work as expected, with a jitterlimited by the FPGA clock frequency.
7. Trigger Interface Board. 199
Figure 7.50: Delay measurement with 3D3428 delay line
• A complex logic has been developed, which can generate trigger outputs which are synchronouswith a local Level 1 trigger signal, but not with the FPGA clock.
• The trigger type generation worked as expected.
• The trigger rates can be measured in the FPGA.
• The SPI control of external chips, such as the DS1123L or the thermometer worked properly.
• In spite of the board complexity, no crosstalk problems between lines were observed.
• The designed power supplies add very little noise.
In addition, there are two important points to improve in the next prototype version:
• The optical SFP transceivers must be replaced by the ones based on discrete VCSELs and PiNphotodiodes, capable of working with trigger-like pulsed signals.
• The 8 delay chips DS1123LE-200 from Maxim must be replaced by one 3D3428 from DataDelay Devices, with much lower jitter.
Anyway, it must be pointed out that the first TIB prototype fulfils the requirements for theforthcoming integration tests, with only one camera. When the improvements, which are already

tested, will be included in the second TIB prototype, it will be possible to accomplish all therequirements of CTA LSTs and MSTs.

Conclusion and Outlook
8.1 Conclusions
During the last four years I have been working at GAE-UCM, together with other Spanish groupsfrom Ciemat, IFAE and UB and in coordination with other foreign institutions, specially from Franceand Japan, with the aim to build the best possible trigger system for the large and medium sizedtelescopes of the forthcoming Cherenkov Telescope Array. On the base of our previous knowledge andour experience with the MAGIC telescope, we conceived a system with a great expected performanceaccording to MonteCarlo simulations (see section 3.2), and which is feasible to be constructed andoperated.
The proposed trigger architecture follows a multi-level scheme, able to support many of themost powerful trigger techniques: majority trigger, sum trigger, variable trigger region sizes, partialreadout, sliding window, two-thresholds strategies, Colibri, PMT transit time calibration, hardwarestereo trigger and even software array trigger with the digitized data. Such a global architectureis the result of the collaboration between all the mentioned teams mentioned above. Nevertheless,each group developed a different hardware element: IFAE team designed the Level 0, Ciemat teamis in charge of the backplane, UB worked in ASICs and at UCM-GAE we designed the Level 1 andthe TIB, which are the core of my thesis.
The Level 1 implements successfully the required functionalities: it combines the inputs fromsets of clusters and decides if the camera should be triggered or not. It does it in a very short time,with a negligible jitter, complying with the bandwidth requirement and adding very low noise. Itis able to implement the sumtrigger scheme, it supports Colibri (as described in chapter 5) andincludes the necessary hardware to implement the delay compensation system described in chapter6. Several prototypes have been tested with the other systems and the current design is ready forindustrial production. Additionally, the development of the Level 1 produced 2 extra-outcomes:
• Usability of microwave techniques and technologies adapted to short pulse handling. Thetypical spectrum of a PMT output pulse ranges from low frequencies to up to 1 GHz and,at these high frequencies the RF and microwave technologies can be useful. The case of theWilkinson splitters [6] or the use of Schottky diodes are examples of this.
202 8. Conclusion and Outlook
• Patent of a new family of logic gates, able to work with LVDS and other differential logicstandards.
Regarding the TIB, two boards of the first prototype have been designed, manufactured andtested, and the results are very satisfactory. The current TIBs have been able to comply with thevery demanding requirements needed to implement the LST hardware stereo logic, gathering thedifferent trigger origins and generating the trigger type. The use of chains of flip-flops in a FPGAhave showed the expected performance in the delay lines and in the stretchers, and the RaspberryPi has been a good solution to implement the slow control communication and to configure theFPGA. Thus, the current prototypes are useful for the single camera demonstrator tests which willtake place during this year. Two problems with the optical links and the external delays have beendetected, and the solutions are ready to be implemented in the next version of the TIB, which isscheduled to be ready some time before two telescopes will be ready to work together in a stereotrigger scheme.
In short, it can be said that the work carried out during these years has made possible to presentan excellent trigger system, able to comply with the demanding requirements of CTA LSTs andMSTs.
8.2 Outlook
The CTA project is now at the end of its prototyping phase. From 2014 to 2016, prototypesfor large demonstrators and complete MSTs and LSTs will be built, tested and assessed. Thesecomplete prototype telescopes will be also used to test and adjust the trigger distribution system,check the accuracy of the different calibration algorithms (flat-fielding, trigger amplitude, delays...)and to finish the implementation of all the details required for the correct data taking, such as thoserelated with the data format, event building, time stamping, slow control, etc. In summary, all thedetails required to make CTA telescopes work, but which can not be tested without a completecamera, will be implemented and tested in this phase.
Additionally, building these first telescopes implies the first industrial production of severalelements, such as the camera front-end boards and backplanes, and their assembly in clusters withPMTs. These elements must be tested before being mounted in the camera, according to a qualitycontrol protocol which still needs to be defined. Defining the measurements to be done in each step,the acceptable values, and developing the corresponding test setups is an intensive work which alsoneeds to be done in this stage. Part of this work will be subcontracted to companies, but alwaysunder the control of the groups which developed the systems.
All this work will not leave much time for developing new ideas. However, there are two maininnovative lines to be developed, as soon as the other tasks allow us.
8.2.1 Trigger integration in ASICs
One interesting idea, with the aim of reducing the number of components, simplifying the assem-bly, reducing costs and power consumption, is to develop ASICs concentrating the different triggerfunctionalities. Our partners in ICCUB (Institute of Science of the Cosmos, University of Barcelona)
8. Conclusion and Outlook 203
in Spain and our french colleagues at IRFU (Institut de Recherche sur les lois Fondamentales del’Univers) have some experience developing ASICS ([58], [95], [98]), so that we (mainly ICC-UB andCiemat, with UCM and IFAE collaborating in the specification and testing) have taken advantageof their experience and collaboration to design and manufacture ASICs for the trigger.
In this way, one ASIC for Level 0 and other for Level 1 have been designed, and a first versionproduced and tested, while other ASIC for the Level 0 fan-out function is in the design phase.Some functionalities like the ones related with the SPI slow control used in the Level 1 to adjustthe threshold levels have been easy to include, because they have been already implemented forNECTAr. However, the ones related with differential to single-ended conversion or the addition ofanalog signals were more complicated requiring to be redesigned. This was so because several basicfunctions are easier to implement in an ASIC in a different way from how they are implementedwith discrete components. For instance, the Wilkinson splitter functionality can be implemented ina more straightforward way replicating the signals with current mirrors. In general, replicating andadding currents, is preferable when working with ASICs.
Regarding the ASICs manufacturing, Europractice [170] has allowed us to share the silicon waferwith other projects, making the prototype production much cheaper. After the production, theASICs are in the process of being fully characterized to check if they can substitute the Level 1 withdiscrete components.
The GAE-UCM group which I belong, has contributed with the Level 1 ASIC specification andwill also help with its characterization. Before being directly soldered in the front-end board, a firstbatch of ASICs will be mounted on mezzanines compatible with the ones implemented with discretecomponents. In this way, the ASICs can be tested with the front-end boards, and their behaviourcan be compared with the one obtained with discrete components. The GAE-UCM group will be incharge of the production of the L1 mezzanines with the Level 1 ASIC designed by the Ciemat team.The target is to have the ASICs characterized and ready for integration in the front-end boards andin the backplane for the massive production phase, when most of the telescopes will be built. If itis not possible, designs with discrete components are the default solution.
8.2.2 Topologic stereo trigger
In the case of the Trigger Interface Board, there are still a few improvements to include regardingfirmware debugging and software development. As was mentioned in section 7.3, there are severaladvanced functionalities which could be implemented if required, although the baseline which consistsof looking for temporal coincidences between 4 LSTs and gathering the different trigger origins isworking as expected.
One of the most promising improvements is the topologic hardware stereo trigger. As it wasbriefly described in section 7.3.5, it consists of looking not only for coincidences inside a time window,but also for images compatible with Cherenkov showers. Adding this additional condition, most ofthe NSB triggers which happen by chance inside the time window can be rejected, while keeping theγ-ray-like showers. As the trigger rate can be further reduced, it is possible to lower the thresholdsuntil reaching the maximum reading rate again at a smaller energy threshold.
A similar topologic scheme has been proposed for the MAGIC telescopes, which could serve as abaseline design for the CTA LSTs. The first simulations results, whose performance is representedin figure 8.1, show improvements above 20% in the collection area below 100 GeV [171]. In the case

of CTA LSTs, having 4 telescopes instead of only two, an even larger gain is expected. This casewith 4 LSTs is currently under study with simulations.

The practical implementation of a topologic hardware stereo trigger in CTA would require someminor changes in the current trigger hardware. The trigger system presented in this thesis canhandle all the trigger information in a pulse: a trigger pulse means that the trigger threshold has

been exceeded somewhere in the camera, a known amount of time before receiving the leading edgeof the pulse. To implement the topologic scheme, the information about which cluster triggered, orat least which area of the camera was triggered, is required by the Trigger Interface Board to lookfor valid patterns.
There is only one spare line in the RJ45 interface between the TIB and the central backplane(see table 7.1), so in order to send more information to the TIB, this information must come fromother backplanes apart from the central one. Considering this second option, two schemes have beenproposed, which are described in subsections 8.2.2.1 and 8.2.2.2.
8.2.2.1 Sectorization
In these scheme the special backplanes which provide information to the TIB are the 7 onesaround the central backplane. According to the current distribution scheme for the trigger, whenone cluster is fired, it sends its trigger to a neighbour which, in turn, sends it to other neighbourand this process repeats until reaching the central cluster. The path followed by the trigger signalchanges depending on the specific cluster, but always is composed of some “diagonal” jumps untilfinding their corresponding main path (or none if the fired cluster is in the main path), and some“radial” jumps until reaching the central cluster. This is illustrated with red arrows in figure 8.2.
Figure 8.2: Sectorization scheme
206 8. Conclusion and Outlook
This way of collecting the trigger signals means that, any of the six special backplanes surroundingthe central one receives the triggers from a triangular sector which covers 1/6 of the camera. So,once the special cluster which received the trigger is known, it is possible to deduce in which camerasector it was generated. Additionally, if the number of jumps is encoded in the pulse width of thetrigger pulse, it is possible to restrict even more the possible trigger origins to one of the areas withthe same color in figure 8.2. The clusters corresponding to the last two jumps have been colouredwith the same color (i.e. included in the same region) to avoid very small regions, however they canbe divided in other two regions corresponding to one or two jumps away from the special cluster.
With this scheme, as it is described by figure 8.2, the TIB can know in which of the the 37regions of the camera the trigger was originated. This information can be codified with 6 bits andbroadcasted through the optical links to the other LSTs. So, considering 4 LSTs, the TIB canmanage a table with 374 = 1874161 possibilities: some of them will be accepted as images producedby a γ-ray shower, while others don’t. If this granularity is not enough to get good results from thetopologic trigger, the triangulation scheme can be used.
8.2.2.2 Triangulation
The triangulation scheme is more complex, but it allows to know exactly which cluster was trig-gered. When a cluster is triggered (orange in figure 8.3), it distributes a signal to all its neighbours,which in turn send their signals to their surrounding neighbours and so on, generating a triggercircular wave front which expands throughout the camera (red circumferences). The number ofjumps is codified in the pulse width, so the special clusters (red ones in figure 8.3) can know howfar from them a trigger has happened. In this way, the TIB, which will be additionally connectedto these special clusters, also knows how far from each special cluster a trigger happened and cantriangulate the position of the trigger origin.
The propagation of the trigger wave throughout the backplanes network would be independentfrom the standard trigger propagation, and could be done using spare lines in the connectors betweenneighbour clusters. However, the way in which it could be propagated to prevent the wave fromcoming back, or how would it solve special cases like two clusters triggering at the same time is stillunder development.
Additionally, knowing which cluster from the 265 in a camera was triggered in the 4 telescopesmeans 2654 ≈ 5 · 109 possibilities to be analyzed by the TIB FPGA. This is probably too much totake the decision with a look-up table in a short time, so maybe some kind of region reduction wouldbe required, partially loosing the greatest advantage of this scheme.

Table B.4 contains all the costs required to manufacture one trigger interface board module.Unlike in the case of Level 1, the TIB is an independent module, so the costs of manufacturing thePCB and assembling the components must be always taken into account. Additionally, there willbe also some fixed costs gathered in table B.5 to be shared between all the manufactured boards1. The total number of TIBs will quite smaller, so from the manufacturer point of view all of theboards will be considered as prototypes, which means more expensive prices.

Table B.5: Fixed costs of the Trigger Interface Board
The costs of table B.4 correspond to the first TIB prototype. The costs of the final version whichwill be installed in the telescopes cameras will be slightly different. For instance, one of the mostexpensive components are the optical transceivers (c.a. 40 ACeach), of which there are 12 units inthe prototype. In the real case, it is very unlikely to have more than 4 LSTs in each observatory,so there would be only 3 neighbours in the case of LSTs and 0 neighbours in the case of MSTs.Additionally, other optical link is an spare and other is reserved to check the performance of theoptical delay of the signals. So in fact, only 5 from the 12 optical transceivers are strictly requiredfor LSTs and 2 for MSTs, which involves saving up to 280 ACin the boards installed in LSTs and 400ACin the ones placed in MST cameras. As was explained in section 7.4.2.2, all the TIBs will have thehousing for the 12 transceivers mounted, but only the required transceivers will be installed. In thesame way, another significant costs are the delay chips, which need to be tested before deciding touse them in the final version.
Appendix C
Reliability
In a large project as CTA, it is very important to estimate the reliability of the different systemsproperly in order to foresee the number of spares required, the human resources which should bededicated to reparations, and in sum the budget required for maintenance. With this aim, all thesubsystems must provide to the system engineers with their reliability estimations. This appendixcontains the reliability estimations for the Level 1 (table C.1) and the Trigger Interface Board (tableC.2). For this estimations, the Middle Time Between Failures (MTBF) or the Failure In Time(FIT) information provided by the manufacturers of the different active components has been used.However, for the pasive components this information is sometimes difficult to find, and due to thehigh number of elements and the different manufactures which can produce equivalent components,getting the MTBF or the FIT from the manufacturers would be and endless task. For this reason, thereliability of the passive components have been estimated with the generic prediction models includedin the FIDES guide[172], instead of with their specific data. A free software tool implementing theseprediction models have been used [173], as shown in figure C.1.

Table C.1: Reliability estimation for the Level 1, only com-ponents
According with table C.1, An average of only 1 failure in each 2391 years is expected. Thisnumber is very high, because it corresponds to a relatively small subsystem. Considering that therewill be 265 Level 1 modules in each camera, every camera will suffer one Level 1 failure in 9 years asan average. Additionally, it is important to notice that the estimation of table C.1 corresponds onlyto the components, considering that the Level 1 is integrated in the front-end board. If the Level 1is installed as a mezzanine, the failure rate of the connectors must be taken into account. Accordingto FIDES model, for a 52 contacts SMD connector, a MTBF of 1.13 ·108 is expected. Once includedin the estimation, an MTBF of 1.53 · 107 hours (1745 years) is obtained for the Level 1 mezzanine.

Table C.2: Reliability estimation for the Trigger InterfaceBoard
In the case of the Trigger Interface Board, a MTBF of 8.65 · 105 hours (99 years) is obtained.This is much smaller than the MTBF of the Level 1 because the system has more components andbecause there are two components specially critical: the SFP transceivers and the Raspberry Pi.
It is difficult to find reliability information about the Raspberry Pi, but it is known that itsreliability is limited by the MTBF of the SD card used as hard disk drive (to store the operatingsystem, the slow control software, etc.). The best SD cards have an MTBF of around 2 millionhours. Nevertheless, this estimation considers that the SD card is read and write quite often, as inthe case of using it in a photograph camera, reaching the maximum number of times that the cardcan be written. In the case of the Raspberry Pi used in the TIB, the SD card contains the softwarerunning in the computer, but it is not used to store data, so it will be written only for softwareupdating. Therefore, a longer lifetime for the SD card could be possible.
Regarding the SFP transceivers, there is not much to do to enlarge their lifetime, apart fromavoiding to work at high temperatures. Anyway, as there is only one Trigger Interface Board percamera, 99 years of MTBF is acceptable.
