| 2018-11-21 | Seiya | ECC went to error state |
I used ClusCo@tcs01 for the monitoring, all the plots except "Amp. Temp" was updated indeed. After that, I did init7 from ClusCo@cacooperator and waited the update of "Amp. Temp" plot. At that time, ClusCo@tcs01 showed timeout, so I realized I cannot ping these modules and relay current went to 0 and ECC state went to error state(4). I powered up again and ECC status went to 2(ready) as usual, but relay current was 0. Taka explained why relay current was still 0 as below; When ECC goes to Error state, relay modules are also in a strange state. You need to reset relay modules as well. However, even if you go to "safe" state in ECC, relays are still powered (not bus bars, but relay modules). That means, "safe" does not reset relays. Lea explained why ECC went to error as below; Maybe what is possible also is that you lost the slow control connection during few seconds and then get it back without realising. Then If the modules are ON and that we lost the slow control connection, ECC goes to error and the relay current will remain at 0 as Taka explained.

| 2018-11-20 | Daniel K., Seiya | ClusCo monitoring restart | ClusCo monitoring map was not updated after the shutdown of tcs01. We contacted with Carlos and Carlos and they restarted it again.Now it works. | ||
| 2018-11-20 | TCS01 shutdown | One of the memory cards of tcs01 is damaged and will be replaced
by an authorized technician today starting 9am La Palma time. We will shutdown the server before that and once the card is exchanged we start it up again. | |||
| 2018-11-19 | Seiya, Daniel K. | Test pulse data with DragonDaqM(LegacyDAQ) | We took test pulse datat with the following conditions;
1) 300Hz, ROI=1024, trigger was generated by mod265 (for reproducing the problem)
2) 100Hz, ROI=1024, trigger was generated by mod265 (suggested by Taka)
3) 300Hz, ROI=1024, trigger was generated by mod265 (suggested by Taka)
4) 100Hz, ROI=1024, trigger was generated by mod265

| 2018-11-19 | Seiya, Daniel K. | 24V supply problem | We powered up the camera with the usual procedure, but only one busbar(the 4th one) worked and others didn't work. We tried this procedure again, but the result is the same(only the 4th busbar worked).So we switched off and on the camera breaker around 15pm. Fan didn't start to work at first, so I switched on and off the breaker again and fan started to work. After that we can power up the whole cameras.
| ||
| 2018-11-13 | Mitsunari, Daniel K. | Software deployment | All the setup (except the uaexpert for ecc, tib and ucts) to control, monitor and take data with the camera was moved to the LST_CALP iMac (+ 1 screen) of the commissioning container. | ||
| 2018-11-12 | Mitsunari, Daniel K. | Test pulse data with DragonDaqM | Test pulse data were taken by DragonDaqM triggering by the module 264, which did not have a test pulse on 11-09. | ||
| 2018-11-12 | Mitsunari, Satoshi | Connect tcs07 to White Rabbit | WR switch management port and Management switch (mgtsw2 port 42) are connected by a Ethernet cable. Mitsunari tried to change the IP of the WR switch to 10.200.10.140, which is in VLAN 1001, but I failed. The WR interface file dot-config was not found in spite of the WR manual. Even when we created the file by ourselves, it was lost after rebooting. | ||
| 2018-11-12 | Mitsunari, Daniel K., Carlos Diaz | Software deployment | Installing and compiling caco, cacoconsole, cacogui on tcs01 under /home/ifae/development. Compiling /home/ifae/clusco on tcs01 and adapting monitoring from CIEMAT. Setting up one additional screen for monitoring to the imac (monitoring computer), adding two forms (one for powering on the camera, one for shutting it down) to be filled by the operators. | ||
| 2018-11-09 | Mitsunari, Daniel K. | Test pulse data with EVB | Test pulse data were taken by EVB waiting PPS reaching all modules for 2 s. For the read depth 40, DAQ seemed to be successful. For the read depth 1024, however, the data were not stored. | ||
| 2018-11-09 | Mitsunari, Daniel K. | Test pulse data with DragonDaqM | Test pulse data were taken by DragonDaqM waiting PPS reaching all modules for 2 s. The waveform data of six modules besides the central one were checked, and five modules had test pulses though the other module (No. 0) did not. | ||
| 2018-11-03 | Mitsunari | Test pulse injection timing | Test pulse data were taken with L1 threshold which all modules can produce camera trigger. According to the data, the timing of test pulse injection distributes aver ~70 ms. Test pulse injection rate: 1 Hz, Read depth: 40, Sampling speed: 1 GHz | ||
| 2018-11-03 | Mitsunari | Test pulse injection timing | Test pulse data were taken with L1 threshold which all modules can produce camera trigger. According to the data, the timing of test pulse injection distributes aver ~70 ms. Test pulse injection rate: 1 Hz, Read depth: 1, Sampling speed: 5 GHz | ||
| 2018-11-02 | Mitsunari | Test pulse data with EVB | Data for investigating the test pulse issue were taken with EVB but seems to be failed. This should be inspected. Pulse rate: 300Hz, Read depth: 1024, Event number: ~9000, /fefs/onsite/data/20181102 | ||
| 2018-11-01 | Mitsunari | Large data with random trigger | Data of ~10^5 events were taken for pedestal random tirgger, EVB, the read depth 40 slices, and the dealy 3528 ns. The data are stored in /fefs/onsite/data/20181101.
| ||
| 2018-11-01 | Mitsunari | Avoiding TIB State 255 | The TIB state can go to 5 without resetting at state 255 by a combination of reseting TIB at state 0 and configuring dragons without resetting BPs.
Mitsunari repeated this procedure four times and succeeded for all of them. DAQ also seemed to be successful at the last trial. (At the first three trials, DAQ failed because of another reason.) | ||
| 2018-10-31 | Mitsunari | TIB State 255 problem | init7 without BP reset at the beginning was tested. The first trial failed, namely, the state turned out to be 255. However, TIB state directly went to 5 In the second trial, when TIB was Reset just after turning on Camera. This behavior should be confirmed later. | ||
| 2018-10-31 | Mitsunari | Check for test pulse synchronization | It should be confirmed whether TenMHz counter vaue is idential among the modules for each test pulse event. Data for the check were taken by DragonDaqM with 300Hz. L1 threshold was set so that only the central module sent triggers. The data were stored in /home/dragon/IACMiniCamSetUp/DragonDaqM/Data20181031. TenMHz counter appeared to be synchronized, but it should be confirmed. | ||
| 2018-10-31 | Oscar, Mitsunari | PDB Fixation |
PDB fixation: the fixation of the from plate is done know throw a screw and nut fixed to the back plate using a mixture to attach metals (Pattex Nural 21) and an additional nut to fix the front plate. We have started Modules twice with one hour break in between. Both times all Dragons and BP went up. | ||
| 2018-10-30 | Taka, Mitsunari, Julien, Dirk | Random trigger runs with EVB |
Two runs (#30, #31) taken at various trigger rates as documented in Run Catalog and Slack. Corrected pixel map implemented (spiral numbering).
| ||
| 2018-10-29 | Oscar, Taka, Mitsunari | Power up |
The Dragon with IP 10.1.6.28 (3rd column starting by the left from outside, 5th modules from below) was put in the busbar powered by relay 1 instead of 0. In exchange, module in 4th column 5ht from b below was put in the relay 0 instead of relay 1. Camera was powered up only once and all modules and BP went up.
| ||
| 2018-10-27 | Taka, Mitsunari | Random Trigger |
We took the random trigger. Following the instruction with Lea, random trigger could be easily produced. With DragonDaqM, 300 Hz injection -> 300 Daq rate. 1k Hz-> 783 Hz 3k Hz-> 1162 Hz 6.5k Hz -> 1303 Hz. With EVB, we first tried with 6.5 kHz. Then EVB crashed because of buffer full. But busy state of modules was 03, which means EVB are connected and modules were busy. To recover from this state, we had to reboot Dragons. A few minutes later, Carlos Diaz called us. The current consumption at bus bars are ~10Amp higher than usual. Normally 25-27 Amp but after rebooting Dragons, it was 35 Amp. We shutdown the 24V. After 10 min or so, Carlos allowed us to restart. All Dragons could be communicated from cacoserver, but not from Osaka. ip link set p*p* down/up didn't help. We rebooted Osaka. Then Osaka could ping to all (but one) modules. However, EVB didn't work. Later we learned from Dirk and Julien that we had to do sudo modprobe -r ixgbe; sudo modprobe ixgbe
| ||
| 2018-10-27 | Oscar, Laia , Taka, Mitsunari | Power up |
After checking that Dragon and BP regulators can stand input voltage above 30 V, we increased the power provide by the Power Supplies to 27.5V (the same for the 8 Power Supplies). With this configuration, the voltage while ramping up increase up 20.3 V and then only decreases to 19.8 V for about 1 ms. This should be completely find for the Dragons. We power up the camera with the ECC 10 times. All BP went up all times. Only one Dragon (always the same) does not power up the first time after a ~1 hour break (tried two times), after this first power up all Dragons power up. | ||
| 2018-10-26 | Taka, Mitsunari | TIB state machine. |
We tried to solve the "State 255" problem in TIB. Luis Angel suggested to configure modules at state 2. We followed his instruction, but we reached state 255. So we tried modules configuration at state 0. Same result. We tried module configuration at state 4, resulting in the same state 255. We also tried to see the test pulse postion to the center of the readout window. But we could not see the test pulse at all. Delay setting in TIB or backplane is not correct.
| ||
| 2018-10-26 | Oscar, Laia , Taka, Mitsunari | Power up |
The drop in the voltage is due to a current limit in the circuitry of the relay. Increasing the voltage of the power supplies should rise the value of the dip in the voltage so that it does not reach 18V. We measure again the transients for relay 0 with Power Supply at 24.98 V as reference. We increase the voltage of Power Supplies to 25.25 V, the dip is about 100 mV higher. | ||
| 2018-10-25 | Taka, Mitsunari Yusuke | Event Mixing |
We understood the origin of EventMixing. It is due to the slow control command "Dragon - Start" after "Enable Trigger" in TIB. "Enable Trigger" should have been after "Dragon Start". This is dangerous actually. Mistake will be noticed only during analysis.
| ||
| 2018-10-25 | Oscar , Laia | Power up |
No water was found inside the camera. We measure the voltage at the output of the Redundancy modules: 24.98 V We connect a Current sensor between master bus bar and relay 0. We power up relay 0 and measure transient for both current and voltage: - Voltage shows a drop of around 1.5 V once it arrive at 20V, which is afterward (4 ms) recovered and keeps increasing until about 24.5 V - Current increases steadily with a small slope change on the drop on the voltage happens. It also show a drop of about 30% when the voltage reach 24.5 V that it recovers after about 80ms after The voltage reduction for 4ms brings the voltage very close to 18V, and some times may go slightly down. The same is observed in relay 1. | ||
| 2018-10-21 | Taka, Mitsunari, Yusuke | Timing Calibration. |
We tried to see the test pulse in the center of window. But we did not succeed. DAQ was with EthDisp from Taka's macbook through slow control network. We need to understand the delay in TIB and backplane. Since it was already 5:50 pm, (though we announced that we use camera until 5:00 pm) we had to shutdown. We kept 230 and 400V on, chiller on, only 24V off. | ||
| 2018-10-21 | Taka, Mitsunari, Yusuke | Event Mixing Test |
To confirm again the event mixing problem, we took data with the LegacyDaq. After init7.uic, we injected the test pulse in the central module with 300 Hz. TIB could see the rate properly. We took 20000 events. After that, we tried to take data with EVB, but it was not successful. EVB could not connect to all modules. We had the same problem a few times in a row. One of the reasons was dead ports in Osaka. Sometimes, ports in Osaka sleep without obvious reason. This is actually critical problem. We need to investigate further. Finally we gave up to take data with EVB. | ||
| 2018-10-21 | Taka, Mitsunari, Yusuke | TIB/UCTS study |
After power up, we tried to initialize TIB. But state didn't reach "5". After state 4, if we enable trigger, state went to 255. We knew that the RJ45 cable on the WR was damaged by the rack door. We changed it to new cable. We also used a different port in WR (port 8->5).And we reset TIB. Then with the standard procedure, state reached 5. We were happy. Just to be sure, we changed back to the damaged cable and retried. Then state was again 5. So, the reason was not the cable. But "Reset" of TIB was the key. After initializing PMT modules, TIB didn't work well. It didn't send back the trigger. Since temperature was too high (BP 35 deg.) We had to switch off the 24V. During this break, we changed the WR port from 5 to 8. After power up, we repeated the procedure. Again, TIB didn't send back the trigger. But, TIB reset helped. So, currently, startup recipe is that 0->1->2->3->4->255->TIB Reset->0->1->2->3->4->5->configure modules -> TIB Reset -> 0 -> 1 ->2 ->3 ->4 ->5.

| 2018-10-21 | Taka, Mitsunari, Yusuke | Restart the Camera. |
Before powering up 400V for the first time since last Tuesday, we examined the camera visually. Camera is properly parked. There was a water condensation on the camera body. The platform is not perfectly closed. There was a 2 cm gap between left and right. But it is not dangerous for us. At 11:45, we applied 400 V putting the breaker at the Drive container. After 15 min of stabilization, we started 24V from ECC (state ready). Then, we realized that TIB and UCTS do not respond on Ping. It was because dhcpd on tcs01 was dead. Also, uctsd on Osaka was dead We restarted dhcpd and uctsd and switched off and on 24V. Then, TIB, UCTS could be booted.|

| Dirk, Taka, Julien, Seiya, Léa | Data acquisition |
- Pb with the ClusCo on tcs01. The root propagation for the BPs for the trigger doesn't work. Using exactly the same script it works on CacoOperator. - We validate for 3 fibers the new connections to the dataswitch fiber. Eric is fixing the one missing or broken. So for now only the right part of the camera is used for data acquisition - No TIB/ UCTS - Few runs were taken with no external trigger from TIB. 3 Modules didn't appear busy but didn't sent any data. In those test the busy from the CBP was cut. Those missing modules have to be investigated in more details but due to a lot of slow control deconnection problem and high temperature in the camera it was not possible. Script used in CLusCo: init7_noextTrigger_Test.uic. To not cut the busy, name is: init7_noextTrigger_noBusyCut_Test.uic - One try with no external trigger and clock but with the CBP delivering the clock and pps and using 10 MHz clock as default clock for the dragons. L1 local Trigger didn't generated. No we come back to a configuration of dragon on their local clock but this issue has to be investigated. Script used in CLusCo: init7_noextTriggerClock_Test.uic | |||
| Dirk, Taka, Julien, Seiya, Léa | Too high temperatures in the Camera |
- Limit fix to 27 for the aire temperature inside and 35 for the BP temperature. Pression also get some alarms - During the day, due to high temperatures we have to gotosafe to wait for the camera to cool almost 11 times but never the BP max temperature went more than 34 degree. The air inside reach at the maximum 26.5. | |||
| Dirk, Taka, Julien, Seiya, Léa | ECC lost connection (2 times!) |
- In the afternoon, 3 lost of ECC slow control communication due to the interruption between IT-Container/Driver-Container. Miscomunnication with AMC people... First time, temperature was already high in the camera, we had to switch OFF the 233 and 400V for security reasons. Two other times, we get the ECC connection back quite fast and ECC was in the same state that when the connection was lost meaning state 2 ready. Just no more current in the pulse bar so we have to gotosafe and gotoready both times. After that the current was -247 in the pulse bar... Not understood for the moment - The second interruption happened, when the Moxa switch was reconnected, probably not correctly configured. It was disconnected again. Presently this impacts AMC and drive operation, until the Moxa can be reconnected. | |||
| Léa, Taka, Julien, Seiya, Dirk | Discovered SLOW control fiber lost, fibers changed connection recover | Interruption. Using UCTS section for replacement. | |||
| 2018-10-11 | Eric, Armand | Cable splicing | UCTS fibres ready and checked. | ||
| Léa, Taka, Julien, Seiya, Dirk | DATA5-upstream broken | Located between DC-PP. and IC-PP. Eric is going to have a look on Friday, when working on the other (spare) fibres. | |||
| Léa, Taka, Julien, Seiya, Dirk | Found correct order of DATA1-DATA6 | We eventually found that the fibres DATA1-6 were connected in (exactly) wrong order to the camera, which lead to a mismatch of switches/modules with respect to interfaces/addresses in osaka.
This is an item for our "learned lessons": The indoor fibres had been labelled (switch-interface), but stayed in Mirca. The new fibres had been confectioned at ORM, and labels had to be "guessed" in one way or the other. |
