| 2017-6-14 | Alba, Daniela, Seiya | DAQtests ModuleQC | LSTDAQ (Daisuke) and iDAQ (Marseille group) test until the afternoon. Flushing back official firmware version (c13) and long-term run of MiniCam 11 for 2 hours. | ||
| 2017-6-13 | Alba, Daniela, Seiya | ModuleQC DAQtests | Long-term monitoring of MiniCam 11. LSTDAQ tests with Daisuke from remote. At some point we lost connection to one module due to overheating, it seems. Please see the plot on the right (monitoring_modules.png). We switched off the Dragons, waited about 15 minutes and switched on again. Afterwards everything worked fine. In the evening we flushed the newest firmware (d00) to all the modules for iDAQ tests tomorrow morning. | Summary DT vs L1 L1 vs DAQ DAQ Ratio

| 2017-6-12 | Alba, Daniela, Seiya | DragonQC ModuleQC | Setup and start operation of MiniCam 11.
We broke two mezzanines by removing/ inserting the corresponding module from/ into the camera holder. Mezzanine 253352: Missing components are C133 and C2. Mezzanine 068121: Missing components are C133 and L1. We exchanged these mezzanines with 091237 and 117XXX. During the setup we identified two broken Dragon boards: 1-141 and 1-32. We could not establish communication with them. Checking further their power consumption was too low (34 mA instead of ~700mA). Seiya found out that filters F1 are broken on both boards. 1-32 actually passed the Module QC successfully already. We wanted to retest it, since there was a problem during the DragonQC. Taka and Seiya found a problem and changed the MAC address for that board. So something must have happened afterwards. |

| 2017-6-9 | Alba, Daniela, Scott, Seiya | ModuleQC | Testing and implementing of Backplane methods. Long-term run of MiniCam 10 during the whole morning and dismounting it. | ||
| 2017-6-8 | Alba, Daniela, Scott, Seiya | ModuleQC DAQtests | LSTDAQ tests with Daisuke from remote. Debugging of L1 and backplane algorithms in ClusCo. Partly done with Gustavo from remote. Long-term run of MiniCam 10. | Summary TrigRate vs Dt DaqRate vs L1 rate DaqRatio vs L1 rate | |
| 2017-6-7 | Daniela, Scott, Seiya | DragonQC ModuleQC | DragonQC and Long-term run of MiniCam 10. There were 3 PACTA IDs missing in the PMT MySQL data base. We had to find them by hand thanks to the help of an excel sheet with all PMTs sent by Daisuke. Dismounting of some LOCTITE fixed PMTs on SCB 0203. This SCB will be taken back to Japan since it showed some strange behaviour for the test pulse. The issue will be investigated there. | ||
| 2017-6-6 | Alicia, Daniela, Daniel, Pepa, Scott, Seiya | ModuleQC DAQtests | Long-term run of MiniCam 9 the whole morning. Set up of MiniCam 10 in the afternoon. | ||
| 2017-6-5 | Daniela, Daniel, Scott, Seiya | ModuleQC DAQtests | Module 2-076 showed slow connection and was repaired by Taka and Seiya. It was due to incomplete SiTCP parameters written in the EEPROM. Doing DAQ tests with Daisuke from remote.
Long-term run of MiniCam 9 for two hours. |

| 2017-6-1 | Alicia, Daniela, Daniel, Pepa, Seiya | DragonQC ModuleQC MCValidation | Operation of MiniCam 9 started. We started with the DragonQC and in parallel we modified the new cooler to be a nice spot cooler. During DragonQC we found one module with very slow response (2-046). We exchanged the Dragon board at the module through board 1-098. The slow one (2-046) will be send back to Italy. | ||
| 2017-5-31 | Alicia, Seiya, Daniela, Daniel, Pepa | Module QC | Long term monitoring MiniCam 8 in the morning. We encountered several problems:
1.) Spot cooler failed several times and started heating instead of cooling. Switching on and off recovered it. 2.) We lost connection to the filter wheel server and realized it quite late. Because of this we lost some long term monitoring data. 3.) In the monitoring we lost shortly the communication to the clusters 2-029 and 2-022. At the end of the day we mounted MiniCam 9. Then we went shopping for a new cooler. |
||
| 2017-5-29 | Alicia, Seiya, Daniela | Module QC | Long term monitoring of MiniCam 8. | ||
| 2017-5-26 | Andrea, Seiya, Daniela, Daniel | Module QC MCValidation | Operation of MiniCam 8 started. Since yesterday we are using again the script MonitorClusCo.sh to monitor the temperature of the modules. Like this we realized that the spot cooler started to heat the MiniCam at some point. Restarting spot cooler few times helped.
For MCValidation we performed successfully L1 Trigger Efficiency tests with three modules. Data to be analyzed and distributed. |
||
| 2017-5-25 | Alicia, Andrea, Seiya, Daniela, Daniel | Module QC | Long term monitoring of"bad camera" = MiniCam 13. All "bad" boards could be recovered through soldering by Andrea or through changing of suspicious mezzanines.
2 boards failed DragonQC: 10.1.4.3 and 10.1.0.32. Taka and Seiya will investigate the problem. We successfully dissolved LOCTITE by hand and exchanged 3 broken dragon boards that Andrea will take to Italy for fixing. We exchanged boards 2-054: showed slow connection --> NEW 1-92 2-129: swapped mezzanin connector --> NEW 1-126 2-039: cap broken --> NEW 1-127 Set up of MiniCam 8 started. |
||
| 2017-5-24 | Alicia, Andrea, Seiya, Daniela, Daniel | Module QC | Mounting of "bad camera" = MiniCam 13. Here we put modules which were soldered by Andrea or had suspicious mezzanines. Testing IPR scan on the desk we found negative pulses for several mezzanines. Under investigation now. | ||
| 2017-5-23 | Alicia, Andrea, Seiya, Daniela | Module QC | MiniCam 11 checked for soldering and red caps glued. Seems that yesterday's power cut affected the filter wheel settings. During the morning we performed the long term monitoring. After checking the plots we realized that the filter wheels didn't move. It took us 2 1/2 hours with great help of Andrea and Taka and Yusuke on skype to recover the filter wheels. | ||
| 2017-5-22 | Alicia, Andrea, Daniela, Seiya | Module QC; Fixing missing soldering; flushing firmware | Taka left and Seiya joined today. Seiya flushed missing firmware to a whole MiniCamera (version c13). Andrea fixed boards with bad soldering. One module (1-67) found with loose main capacitor --> Andrea fixed it. This board doesn't show signal using EthDisp1024 in the calibration channel. Problem? Long term monitoring of MiniCamera 7. Soldering checked and red caps glued to boards in MiniCam 10. There was a power cut in the lab. Our power line was not affected, but the power line of RaspberryPi for the filter wheels. We realized it at the end of the day. So 1 hour of long term monitoring is not useful, sorry. | ||
| 2017-5-19 | Alicia, Andrea, Taka, Daniela | Module QC | Andrea fixed soldering for one board for which the L0 rate scan failed during QC. After fixing, L0 rate scan worked. During the next days he will fix the missing soldering for the remaining boards. Start QC of MiniCamera 7. | ||
| 2017-5-18 | Alicia, Andrea, Taka, Daniela | Module QC | Checking soldering and gluing of security caps; Finishing QC of MiniCamera 6; Setting up of QC of MiniCamera 7. | ||
| 2017-5-17 | Alicia, Andrea, Taka, Daniela | Module QC, MC validation | Checking soldering and gluing of security caps; continuation of QC of MiniCamera 6. Measurement for MonteCarlo group: Gain measurement with NSB --> Gain shows stable behavior. | ||
| 2017-5-16 | Alicia, Andrea, Taka, Daniela | Module QC | Daniela arrived. Continuation of QC of MiniCamera 6. Start checking the soldering of the connectors of the Mezannine pins for all modules. Find corresponding list under documents. Our suspicion: Rate scan might fail because of missing soldering. Gluing of red security caps for the capacitors.

| 2017-5-15 | Alicia, Andrea, Taka | Module QC | Daniele and Tsutomu left Tenerife. Instead, Alicia and Andrea joined, they both are fantastic. We did Dragon-QC of 4th and 5th batch because Taka forgot to do that. Andrea investigated the reason for Rate scan failure of Module 205 and 237. Communication between 237 and mezzanine worked, while 205 could not make SPI communication. We will investigate further tomorrow. | ||
| 2017-5-12 | Taka, Tsutomu and Daniele | Module QC and EVB | We performed long term monitor for 5th Mini Camera again. We assisted EVB test. We finished to upload the module information of 1st - 5th batch to MySQL database. The QC of 5th batch was done. We installed new 19 modules in Mini camera holder. | ||
| 2017-5-11 | Taka, Tsutomu and Daniele | Module QC and EVB | We performed long term monitor for 5th Mini Camera. We assisted EVB test. 37 modules were attached a capacitor protection. Tsutomu destroyed one dragon board. Module ID is 439.
We forgot to start filter server after rebooting Osaka. This is why long term pedestal data was taken with laser on. |

| 2017-5-10 | Taka, Tsutomu and Daniele | Module QC | We performed rate scan for 5th mini camera. The results of IP205 and ID237 are not usual. Since the mezzanine boards, which these two board have, worked well in previous batch, This can be thought dragon's issue. | ||
| 2017-5-9 | Taka, Tsutomu and Daniele | Module QC | Module QC of 5th Camera | ||
| 2017-5-9 | Taka, Tsutomu and Daniele | MC validation, Module QC | We always monitor the trigger signal going from TIB to Central BP using Osciloscope. Today, during rate scan, big noise appeared in the scope, with 2 V amplitude with ~5 MHz (not very fixed). We were very worried about it but it suddenly disappeared. Shit at, 13:43, it happend again for 10 seconds and gone. | ||
| 2017-5-8 | Taka, Tsutomu and Daniele | MC validation, Module QC | When we powered the modules for the first time, the communication with Dragon 10.1.4.37 was not established. When powered on again, it was established. Could be a problem, could be not. We will keep an eye on it. | ||
| 2017-5-8 | Taka, Tsutomu and Daniele | MC validation, Module QC | Trigger efficiency test with several pixel pattern for MC validation. We finished the QC for 4th mini camera and installed 5th 19 modules in mini camera holder. | ||
| 2017-5-5 | Taka, Tsutomu and Daniele | Module QC | Second long term monitor test for 4th mini camera | ||
| 2017-5-4 | Taka, Tsutomu and Daniele | Module QC and MC validation | We performed rate scan and long term monitor test. Daniele analysed jitter of PMT for MC validation. | ||
| 2017-5-3 | Taka, Tsutomu and Daniele | Module QC and MC validation | We took 2 hours of pedestal run with the 3rd batch and switched to 4th batch. Rate scan and long term monitor will be performed to morrow. The rest is finished. | ||
| 2017-5-2 | Taka, Tsutomu and Daniele | Module QC and MC validation | Taka improve a software which is used to analyse long term monitor of mini camera QC. Tsutomu measured and analysed the data to estimate afterpulsing spectrum for MC validation. The data was taken with nominal voltage and L1 local trigger (no TIB). Daniele worked NSB scan for gain stability. This is also a part of work of MC validation. | ||
| 2017-4-28 | Taka, Tsutomu and Daniele | Module QC | We performed long term monitor test for 3rd mini camera. Since we forgot to turn on cooling machine, the temperature increased. The maximum SCB temperature was ~ 45 degree. We attached attached a capacitor protection on the PMT modules using a glue. Tsutomu fixed the linearity program. Take implemented the function, which show the time fluctuation of temperature, for long term monitor test. Daniele analysed NSB data for MC validation. | ||
| 2017-4-27 | Taka, Tsutomu and Daniele | MC validation | Rate scan test show the module ID 331 does not work well. We installed ID248 in 3rd mini camera, instead of ID 311. We measured (a kind of ) T.T.S with L1 mono trigger for MC validation. To adjust pulse position, setting external delay is needed. We found the best delay value is 3535 ns for ROI40 measurement. | ||
| 2017-4-26 | Taka, Tsutomu and Daniele | EVB | We assisted EVB test. | ||
| 2017-4-25 | Taka, Tsutomu, Daniel Mazin and Daniele | EVB and ClusCo development | We assisted French team and Daniela's work. They wanted to test EVB and ClusCo respectively. | https://drive.google.com/file/d/0B0PR0tNrCVoWM2VvU1kzMEduYW8/view?usp=sharing | |
| 2017-4-24 | Taka, Tsutomu, Daniel Mazin and Daniele | Event building | We assisted French team to perform EVB, We set up new PC named "OKINAWA" and changed a configuration of network. You can see a sketch of new configuration in right column. Daniel Mazin fixed the issue of newest clusco. The problem was that just we uesd wrong uic file. | https://drive.google.com/file/d/0B0PR0tNrCVoWb3ozSm90ZVhaZms/view?usp=sharing | |
| 2017-4-21 | Taka and Tsutomu | MC validation | We measured PMT gain with NSB using LED light (red). To enhance NSB level we attached white paper on wall inside dark box. NSB level was 0.5 - 20.0 (150MHz - 600 MHz, 1 us - 40 us). | ||
| 2017-4-20 | Taka and Tsutomu | Module QC, MC validation | We confirmed that the script, which is used to measure the long term monitor, works well. We also did the rate scan and a measurement which calculates the trigger efficiency for MC variation. Regarding the rate scan, we measured the noise level with the following four patterns, HV = 0 or 1000 V and turing on 19 models or only one module. To calculate the trigger efficiency, we fixed L1 trigger threshold and changed the laser intensity using the programs which were used for dragon QC. | ||
| 2017-4-19 | Taka and Tsutomu | Module QC | We found bugs in CheckLinearityIntegrity.C ("attenuation factor file was specified with relative path w.r.t. "AnaToolsTN") and PlotL1Scan.C (hard-coded string "2016" which spoil names of TGraphs. We finished QC of 3rd mini camera. A result of rate scan shows that a mezzanine board connected dragon board 10.1.6.11 does not work. The several PMT modules have the strange summary plots of linearity measurement. Since the measured data seem to be fine, probability this is program issue. | ||
| 2017-4-18 | Taka and Tsutomu | Module QC | Regarding port 7654 issue, when We carried out the script with "ClusCoOfficialDec20", the connection was stable. In addition we found the several bugs, which prevent the QC sequence in some cases, in the script and program (TakeHVGain.sh and CheckSinglepheIntegrity,C ) and fixed them. | ||
| 2017-4-17 | Taka and Tsutomu | Module QC, Orientation(Tsutomu) | Today was first working day to us in this period. We learned a setup of mini camera QC. First we checked whether an external clock works or not. We found that we have to re-configure BP and Dragon (not only dragon board) after truing on TIB. After this, we tried to perform the all procedure of mini camera QC using "StartQC_IC_ET.sh". But we could not finish this. The script never finished to execute ClusCo in the term of fundamental pedestal. A ClusCo log said port 7654 was not established. At the end of today, we could see LD light from PMT when we used L1 trigger and internal clock. | ||
| 2017-3-25 | Shunsuke | Module QC | The Long term pedestal data of the 3rd bench was taken. To investigate the reason of failuare for datataking of the rate scan, I connected the mezzanine of failure modules again, then I tried the rate scan again for a bit. In the result, the new data of 10.1.4.11 was looked well, but it seems that 10.1.6.11 did not be changed. Probably, We must be careful more when we connect the mezzanine. and unfortunately I deleted the data of the rate scan of the 3rd bench by mistake. we have to take data again. | ||
| 2017-3-24 | Yusuke and Shunsuke | Cleaning | The clean room was rearranged completely cleanly. Please see picture!!!!! | https://drive.google.com/open?id=0B6V4naKAxXfUQ0NLRXhXRGM3Nms https://drive.google.com/open?id=0B6V4naKAxXfUM0F6RngtSkVYczQ https://drive.google.com/open?id=0B6V4naKAxXfUaW9odEItbm1KUmM | |
| 2017-3-23 | Shunsuke | Module QC | The long term pedestal data of 3rd bentch was taken about 2 hours, and EVB test were going well. | ||
| 2017-3-22 | Yusuke and Shunsuke | Cleaning | We cleaned the lab. | ||
| 2017-3-22 | Yusuke | Assembly | All modules were assembled , and so March twenty thirds became the module anniversary. | Assembled 235 modules in IAC, and 35 modules in CIEMAT. A total of 270 modules. | |
| 2017-3-22 | Shunsuke | Cleaning | It is gonig well so far. | ||
| 2017-3-22 | Shunsuke | Module QC | The data of 3rd bencth were taken except long term pedestal . It seems that two modules has little problems. one is module already passed but mezzanine is different before. I have to investigate why the data taking did not work correctly. | ||
| 2017-3-22 | Yusuke | Assembly | Assembled 11 Modules (in total 205 modules + 35(CIEMAT) = 240 modules are assembled). Last 30 modules are left. | ||
| 2017-3-21 | Yusuke | Assembly | Assembled 21 Modules (in total 194 modules + 35(CIEMAT) = 229 modules are assembled). Last 36 modules are left. | ||
| 2017-3-20 | Shunsuke | Module QC | New 19 modules were installed in QC setup. Firmware update of dragon worked well. and QC of dragons also was done. but it seemed that one module (IP10.1.5.4) took long time to create TCP communication. So I skippeed QC of that one. Module QC also took long time due to that one module. we should better change that to other. We noticed that connection bewtween Raspberry pi and cameraserver had lost. We had to configure filter wheel again. | ||
| 2017-3-20 | Yusuke | Assembly | Assembled 19 Modules (in total 173 modules + 35(CIEMAT) = 208 modules are assembled). Last 57 modules are left. | ||
| 2017-3-17 | Yusuke | Assembly | Assembled 22 Modules (in total 154 modules + 35(CIEMAT) = 189 modules are assembled). and, I checked the numbers of pmt which I should asseble by next weekend. | ||
| 2017-3-17 | Shunsuke | Module QC | Long term pedestal mesurement for 2nd bench was finished. That's sounds good. However, the Linearity and Ratescan data of some modules are looked strange. It seems that these modules should be measured again. I also analysed the data of dragon QC. | ||
| 2017-3-16 | Shunsuke and Yusuke | Cleaning | We started cleaning a lab. | ||
| 2017-3-16 | Shunsuke | Module QC | I tried dragon QC for one module which I had not taken data correctly yesterday. it was done well. And I operated long term measurement (taking pedestal data every 10 min with/without laser) for 15 times. It was about 2 hours and a half. | ||
| 2017-3-16 | Gustavo and Shunsuke | Back Plane | We configured BP for measuring BP delay test. We succeeded to configure, but there were some modules did not give L1 trigger. we tried to run delay measurement. it did not work well compared to Japanese set up. so We have to understand what is the reason. | ||
| 2017-3-16 | Yusuke | Assembly | Assembled 20 Modules (in total 132 modules + 35(CIEMAT) = 167 modules are assembled) | ||
| 2017-3-15 | Gustavo and Shunsuke | Module QC | First of all, I tried long term pedestal data. But I noticed that the connection to some dragons were lost. (LANSwitch's indicater was not shining.) It seems that the cause of firmware update was a failure. Thanks to gustavo, We were able to update the firmware through jtag cable. Then suddenly it become impossible to connect to dragons. (LANSwitch's indicater was shining.) After examining it, it seems that the correspondence between the interface (name) and the IP address was changed. By modifying this configuration, the problem was solved, but it took many times . I took about an hour and a half to take the long term pedestal deta. Tomorrow I will continue to take that data again. | ||
| 2017-3-15 | Yusuke | Assembly | Assembled 20 Modules (in total 112 modules + 35(CIEMAT) = 147 modules are assembled) | ||
| 2017-3-14 | Daisuke, Shunsuke | Module QC | I mounted new 19 modules, and tried update dragon's firmware with new program. The program worked well for one module on desk, but for 19 modules we can't excute at the same time. Because We can excute program for 9 modules at the same time, next time I tried firmware update each 9 modules. I did also MiniCamQC for 2nd 19 modules, it was done without big poroblems. Tomorrow I'm going to take long term pedestal data. | ||
| 2017-3-14 | Yusuke | Assembly | I finished preparing of all PMT which use in LST1 for module asseble and assebled two modules ( in total 92 modules in IAC ). From tomorrow, I'm going to asseble PMT module at least 15 per day. I don't need thinking anything when I assebling modules;) | ||
| 2017-3-11 | Daisuke Shunsuke | Dragon Firmware programming | After we exchanged all 19 modules to new ones, We run a program to flush the new firmware into all 19 modules at the same time. This was not successful,,, Non of dragon is responding now.. We tested the program with another dragon board on a table but it did not work as well... | We dismounted all 19 dragon boards. Tomorrow we will mount new 19 modules. We will use the previous version python script to program firmware into Dragon. | |
| 2017-3-11 | Daisuke Shunsuke and Yusuke | Trigger mezzanine | When we were exchanging the 19 modules, we realized that some pins on some mezzanine were popped out (see attached photo). Could it be that mezzanines do not like so much mating cycles??? We should clarify this with experts. | https://drive.google.com/open?id=0B6V4naKAxXfUNnY5cHRwZjNMVFNmMGpCdmx1dHpfdXNWWV9Z https://drive.google.com/open?id=0B6V4naKAxXfUWGJQZS1VMk5aUjRwc2tRSWd1eVRwZWNlMEcw | |
| 2017-3-11 | Daisuke Shunsuke Taka | DragonQC | DragonQC of 19 module done. | We can run DragonQC script only when ClusCo is not running. We will do it at the end of the ModuleQC. | |
| 2017-3-10 | Yusuke | Assembly | Yusuke's fingers are aching. He screwed too much every day. | ||
| 2017-3-10 | Yusuke | Assembly | Assembled 12 Modules (in total 62 modules +19(being checked) + 35(CIEMAT) = 116 modules are assembled) | ||
| 2017-3-10 | Yusuke and Seiya | Assembly | Polishing of Al tube done! | ||
| 2017-3-10 | Daisuke, Seiya, Shunsuke and Yusuke | QC | As we wrote yesterday, the long term data taken yesterday was not useful. today we took data of laser and dark 20 times with an interval of 10 minutes. Baseline is to do long term measurement for two days but for this set of 19 module, we consider that they are checked enough. So on Monday we will be going to the second round. | Here three randomly selected summary files : Module Passport ID56 Module Passport ID36 Module Passport ID13 | |
| 2017-3-10 | Daisuke, Seiya and Shunsuke | Test Pulse Injection | We realized today that the function "dragon_tp_freq" in ClusCo did not send command to modules, hence TP frequency was not changing from the default value. In addition we realized that frequency of TP should be set in the unit of 10MHz when running with the external trigger. we modified the dragon_lib.h correspondingly. | ||
| 2017-3-9 | Daisuke, Seiya and Shunsuke | Longterm Pedestal | We modified scripts for longterm pedestal run, and tried taking data. but we forgot to run 'init4ec'. So a delay which we need to take data around pulse was changed. After we used 'init4ec', we can take data correctly. We have to take long term pedestal data again. | ||
| 2017-3-9 | Yusuke, Seiya and Shunsuke | Assembly | Yusuke assembled 12 Modules (in total 50 modules), Yusuke, Seiya and Shunsuke polished 153 Al-tubes whose quality of edge were bad. We want to polish 180 more tubes. | ||
| 2017-3-8 | Yusuke and Seiya | Assembly | Yusuke assembled 10 Modules (in total 38 modules), Yusuke and Seiya polished 100 Al-tubes whose quality of edge were bad. We want to polish 300 more tubes. | ||
| 2017-3-8 | Daisuke | Remote access to CamServ | VPN account prepared. | Daisuke checked with his laptop and he was able to login to CamServ from outside | |
| 2017-3-8 | Daisuke, Shunsuke | Fundamental Pedestal | Takayuki's Pedestal method integrated. Takayuki's was better as expected. | Comparison of RMS of all 133 pixels between Takayukis method and previous method : https://drive.google.com/open?id=0B6V4naKAxXfUZ3hKakF4RzJyVUU | |

| 2017-3-6 | Takayuki | Software | Software for 1) Fundamental Pedestal Table and 2) Dragon QC are ready. | ||
| 2017-3-6 | Daisuke, Shunsuke, Seiya and Yusuke | Device setup | 6000 screws arrived!!!! | ||
| 2017-3-3 | Andrea, Daisuke, Shunsuke, Seiya and Yusuke | QC | We went through almost all steps of QC. * Fundamental Pedestal * HV vs Gain * Single Phe * Nominal Voltage computation (and comparison to the MySQL data) * Linearity @ nominal voltage. * Rate Scan. Today, we focused on the finalisation of QC scripts, hence we did not wait for 1 hour before we start running the QC scripts. |

The point is that, 1) Automatic software worked properly and 2) Optimum filter combination for Single Phe measurement and HV vs Gain measurement selected. | Single Phe :https://drive.google.com/open?id=0B6V4naKAxXfUU0pkRmhOSHBiZVU Charge distributions at different voltage: https://drive.google.com/open?id=0B6V4naKAxXfUYTB2LWZxalFoUGs HV vs Gain : https://drive.google.com/open?id=0B6V4naKAxXfUVDZHTnJFTHlnS2M | |
| 2017-2-27 | Daisuke | Fundamental Pedestal | Pedestal files of today are being SCPed to icrhome02:/disk/gamma/cta/store/MiniCameraIAC/PedestalData/PedTable_20170227_182555_IC_ET_RD40 | ||
| 2017-2-27 | Andrea, Daisuke, Shunsuke, Seiya and Yusuke | Device setup | We have performed linearity scan. Preliminary results are attached. We are plotting the mean of the charge distributions. When the laser intensity is less than few phe level, pedestal in the charge distribution dominates the mean, therefore, points where the attenuation factor(x-axis) less than 10^-2 is not trustable. Probably we will not need to scan full range for the Linearity measurement. Those attenuation factors less than 10^-2 will be used mainly for SinglePhe measurement. | Linearity plot Preliminary : Zoom up:https://drive.google.com/open?id=0B6V4naKAxXfUS3RDYVFQeGtOSEE Full Range:https://drive.google.com/open?id=0B6V4naKAxXfUaGlHNlJFWkxuTEE HG:Green, LG:Red X-axis : Transmittance factor Y-axis : Charge(5ns integral , in ADC counts x 1 ns) | |
| 2017-2-27 | Andrea, Daisuke, Shunsuke, Seiya and Yusuke | Device setup | Serial Port Id of FilterWheel 1 and 2 were swapped. We corrected it from the software side | ||
| 2017-2-27 | Andrea, Daisuke, Shunsuke, Seiya and Yusuke | Device setup | Trigger delay adjusted : 3.845 us | ||
| 2017-2-27 | Andrea, Daisuke, Shunsuke, Seiya and Yusuke | Device setup | We managed to take data with an external trigger. Since the software trigger cannot be delayed in TIB, the signal needed to be delayed by ourself. It was good that the pulse generator has delay functionality, however the pulse amplitude of the second signal line (non-delayed one), which goes to the pulse-generator was too low to trigger the laser. Yusuke Inome has produced a signal amplifier module and it worked!!! | ||
| 2017-2-27 | Seiya and Yusuke | Assembly | Dragon frame assembly : All finished !!! | ||
| 2017-2-24 | Seiya and Yusuke | Assembly | Dragon frame assembly : Only 4 boards left | ||
| 2017-2-24 | Andrea, Shunsuke and Daisuke | Assembly | We assembled ALL SCB-SCBplate as much as the number of SCB plates. There are 24 SCBs not-assembles and 7 SCB plate prototype. If we can borrow a hand-drill, then those 7 SCB prototype plates could be used. But still we need 17 SCB plates more. | ||
| 2017-2-24 | Andrea, Daisuke, Shunsuke, Seiya and Yusuke | Fundamental Pedestal | We took two timesfundamental pedestal data with Dragon InternalClock External Random trigger. Mean of Pedestal RMS ~ 6 (HG) and ~4 (LG) ADC counts. Consistent with the previous studies in Japan!!! | Stopcell Distribution https://drive.google.com/open?id=0B6V4naKAxXfUdzZaTk9RdkZfUEk Stopcell vs ADC https://drive.google.com/open?id=0B6V4naKAxXfUaVltQ0pDRzEyd1k Pedestal RMS : https://drive.google.com/open?id=0B6V4naKAxXfUNUYtRTBfU2pQMXM | |
| 2017-2-23 | Andrea, Seiya and Yusuke | Assembly | We assembled 54 SCB-SCB plate and 30 Dragon board-Al frame today. | ||
| 2017-2-23 | Andrea, Daisuke, Shunsuke, Seiya and Yusuke | Temperature | Temperature went up by ~ 1 deg when we started to take data at 15:25 | https://drive.google.com/open?id=0B6V4naKAxXfUT0dSVndNaG5MdGs | |
| 2017-2-23 | Andrea, Daisuke, Shunsuke, Seiya and Yusuke | Fundamental Pedestal | We took Fundamental pedestal data as they were taken in ICRR, internal trigger and internal clock. Attached are for module 18. Stopcell vs ADC count looks a bit strange. All capacitors are not scanned equally. But overall RMS distributions look not so bad. we did not check for all of them. | Stopcell vs ADC count https://drive.google.com/open?id=0B6V4naKAxXfUMlZ1eEQxRVZHUHM Pedestal RMS :https://drive.google.com/open?id=0B6V4naKAxXfUMktodUJfV3ZMTDA | |
| 2017-2-23 | Andrea, Daisuke, Shunsuke, Seiya and Yusuke | Fundamental Pedestal | We tried to take data with RandomTrigger from TIB while Dragon running with internal clocks so that they will not be synchronized but it was not successful ... (the reason is unclear yet) | ||
| 2017-2-23 | Andrea, Daisuke, Shunsuke, Seiya and Yusuke | Fundamental Pedestal | Random trigger from TIB is not random, it looks like is synchronous to Domino wave... Spikes in the stopcell every 100 ns = 10 MHz | https://drive.google.com/open?id=0B6V4naKAxXfUVlUyYTdmSEVKcVE | |
| 2017-2-23 | Andrea, Daisuke, Shunsuke, Seiya and Yusuke | Device Setup | TCP/IP socket communication between Camera Server and Raspberry pi Filter Wheel controller is ready. | ||
| 2017-2-22 | Andrea, Daisuke, Shunsuke, Seiya and Yusuke | Trigger | Dead time ~ 1500 counts => 1500 /133 MHz ~ 11 us. Probably consistent. Expected ~ 10 us. But what is the jump between 1500 counts and 2300 counts?? |

| 2017-2-22 | Andrea, Daisuke, Shunsuke, Seiya and Yusuke | Fundamental Pedestal | One of the fundamental pedestal data are being scp-ed to icrhome02:/disk/gamma/cta/store/MiniCameraIAC/PedestalData/PedTable_20170222_164041_RD40/ , hoping that Takayuki can have a look at them | ||
| 2017-2-22 | Andrea, Daisuke, Shunsuke, Seiya and Yusuke | Fundamental Pedestal | We have taken two times fundamental pedestal data, Random trigger at 1kHz, 1e6 events, all automatically including TIB configuration. Data are stored under /mnt/cs1/store/MiniCameraIAC/PedestalData/. The disk mounted under /mnt/cs1/ is configured as RAID6 and hence much faster than the system disk. | ||
| 2017-2-22 | Shunsuke | Assembly | SCB-SCB-plate (~20 today, in total ~60 finished) | ||
| 2017-2-22 | Seiya and Yusuke | Assembly | Dragon frame assembly (~20 today), 51 boards left. | ||
| 2017-2-22 | Andrea and Daisuke | Assembly | Polishing of Al-tube in ElectronicLab. We need to ask Juan to open the door. We should not polish in the clean room. We finished ~150 tubes in about two hours. | ||
| 2017-2-22 | Andrea, Daisuke, Shunsuke, Seiya and Yusuke | Device Setup | Temperature stability studied. After 30 min, temperature goes to plateau | https://drive.google.com/open?id=0B6V4naKAxXfUNDJ3WWhIUnF5enM | |
| 2017-2-22 | Andrea, Daisuke, Shunsuke, Seiya and Yusuke | Device Problem (solved) | The spot-cooler stopped working suddenly, and temperature of SCB went as high as 45 degrees. After some inspection, it turned out that it was due to ice formation in the cooler. We waited for an hour and worked fine again. It is very important that we always run ./MonitorClusCo.shand pay attention to the monitored parameters!!! |
||
| 2017-2-21 | Andrea, Daisuke, Shunsuke, Seiya and Yusuke | Device Setup | We apply nominal HV for all PMTs. HV table created from MySQL database. (GetHVfromMySql.cpp) | ||
| 2017-2-21 | Andrea, Daisuke, Shunsuke, Seiya and Yusuke | Software bug fix | There was a bug in the MonitorReport.C. Time Axis of histograms corrected. | ||
| 2017-2-21 | Yusuke | Assembly | SCB push-pin insertion finished | ||
| 2017-2-21 | Seiya | Assembly | Dragon frame assembly , Seiya can do 15 per day. | ||
| 2017-2-20 | Andrea, Daisuke, Shunsuke, Seiya and Yusuke | Software | We managed to take data of 19 modules with the external clock, TIB configured by the Andrea's python script!!!! | ||
| 2017-2-20 | Andrea, Shunsuke, Seiya and Yusuke | Device Setup | We have found that the UCTS board picks up noise, and goes to INIT state, when it touches the metal part on the edge of the table. UCTS board insulated and the problem was gone. | ||
| 2017-2-20 | Andrea | Software | Andrea wrote python scripts based on "python-opcua" package. We can init and stop the TIB via command line. | ||
| 2017-2-20 | Yusuke | Device Setup | Four LEDs for fake NSB are mounted. Need to be checked. | ||
| 2017-2-20 | Shunsuke | Device Setup | Filters have been inserted to the filter wheel. Need to be checked. | ||
| 2017-2-20 | Andrea, Daisuke, Seiya, Shunsuke, Yusuke | Device Setup | SFP+ DA cable is connected between the NIC X520 on the camera server and the Ethernet Switch(Dell x1052). During the work we realized that the other NIC on the camera server(X710) does not like the DA cable due to the vendor lock. | ||
| 2017-2-14 | Andrea, Daniel, Seiya, Shunsuke, Taka, Yusuke, | Device Setup | Camera Server and network switch were set up. Display, keyboard and mouse were borrowed from IAC. We found that there is no SFP+ cable. We may need to buy one. <-- Daisuke brought two cables. No need to buy. | ||
| 2017-2-14 | Andrea, Seiya, Shunsuke, Taka, Yusuke, | Unbox 2nd container & module assemble | Second container arrived IAC in the morning, We unboxed 9 boxes. (One has Ethernet switch and Camera server, others are module holders) After unboxing, we restarted module assemble again. We found 2 SCB connectors within 15 SCBs were broken. We will check tomorrow ALL SCB connectors if they are fine. | https://drive.google.com/open?id=0B6V4naKAxXfUODdKYXZlM1NfUlk | |
| 2017-2-13 | Syeiya, Shunsuke, Taka, Yusuke | Device Setup | Daniel was right. After fixing the BP configuration, trigger distribution worked properly, both sending and receiving. During measurements, we damaged the connector of TIB. We tried to connected the power cable to TIB when power is already coming at the cable. We will not make the same mistake again. We also implemented NSB simulator , i.e., red LED in the dark box. We measured the gain change up to 20 NSB level. But we found that change is less than 0.4%. | ||
| 2017-2-10 | Luis Angel, Syeiya, Shunsuke, Taka, Yusuke | Device Setup | We put 7 modules and tried to distribute triggers. We created L1 trigger with test pulse (or lazar) from non-central module and checked if TIB receive this trigger via central BP. Unsuccessful. We sent Software trigger from TIB and checked if non-central modules can take data. Unsuccessful. 10 MHz and 1 PPS are distributed to all modules and we could data using local trigger (with external ref clock). So the problem is only trigger distribution. We wrote email to Gustavo and Daniel in the evening and Daniel suggested that BP is wrongly configured because now the camera is up-side down with respect to ICRR camera. | ||
| 2017-2-09 | Luis Angel, Syeiya, Shunsuke, Taka, Yusuke | Device Setup | With new BP configuration, we manage to see the 10 MHz and PPS clock with Osciloscope. However, we could not take data with external ref. clock. We wrote many emails to many people, and finally we found that we need to reset dragon after 10 MHz clock from is stabilized. Now we can take data with TIB 10 MHz clock. L1 Trigger from Dragon can be sent to TIB as well. Dragon can also take data from software trigger and random trigger from TIB. It is now also possible to send a L1 signal to TIB, and TIB delays it and send back to Dragon and take data. The best delay (signal comes at slice 20) is 3700. We found many problems such as noise from spot cooler changes the state of TIB, BP register 10 sometimes fails to be configured. Also, TIB send trigger even if Dragon is in busy state. All trouble shooting is summerized below | ||
| 2017-2-08 | Luis Angel, Syeiya, Shunsuke, Taka, Yusuke | Device Setup | OPCUA client from Shunsuke computer is working fine. We tried to take data with external ref. clock (for DRS) from TIB. But it didn't work. Clock is disabled at BP. L1 trigger from Dragon does not reach TIB either. We tried to contact Gustavo, but didn't manage. In the evening, Gustavo told us with email that with new firmware, register definition has changed. | ||
| 2017-2-07 | Luis Angel, Syeiya, Shunsuke, Taka, Yusuke | Device Setup | TIB is now installed. All clock signals are injected. Power is also OK. OPCUA connection via Luis's laptop is also fine. | ||
| 2017-2-07 | Shu, Seiya, Luis Angel | Change members. | Shu left, and Seiya and Luis Angel came. After Shu left, many problem started to pop up. We are sure that Shu is doing something remotely | ||
| 2017-2-07 | Shu, Shunsuke, Taka, Yusuke, Seiya | Device Setup | We tried to increase the laser intensity so that we can check the linearity up to 2000 p.e.. So far, we can go only up to 1200 p.e. or so. Yusuke change the bias current and electrical pulsed amplitude. However, we could not raise it much. We need to find a solution. | ||
| 2017-2-06 | Shu, Shunsuke, Taka, Yusuke | Device Setup | We manage to solve the filter wheel (FW) problem. After fighting with many hours with Raspberry Pi, we reached a solution. After connecting between Raspberry PI USB port and FW serial port, we monitor /dev/ttyUSB0 with "minicom" problem. And then send command to FW via ttyUSB0. First time it always fails, but second time on, it works. Then, we monitor /dev/ttyUSB1, and send command to FW via USB1. First time fails and 2nd time on works. Then, we stop monitoring ports. After that, both ports work perfectly until power of FW is off. It seems "minicom" monitoring settle the initialization problem. | ||
| 2017-2-03 | Shu, Shunsuke, Taka, Yusuke | Visitor | Masahiro, Daniel, Juan, Thomas and Ramon visited the clean room. We explained the setup and discussed a bit for the future plan etc. | ||
| 2017-2-03 | Shu, Shunsuke, Taka, Yusuke | Device Setup | We realized that we forgot to bring a computer for filter wheel. We could control the wheel with our laptop, but cannot use our laptop for ever. We need to find a solution. | ||

| 2017-1-24 | Shu, Shunsuke, Taka, Yusuke | Cabling | Taka negotiated with Juan Calvo to release the hot air in the lab. Juan refused. The hole in the wall of the lab for air release will be made next week. We borrowed a pulse generator from IAC for trigger for the laser. But we discovered that there is no lemo connector at IAC. We asked Javier for help, and he agreed to bring some from LaPalma at the end of this week. | https://drive.google.com/open?id=0B6V4naKAxXfUcHExbVlGM19zOTg | |

Problems and trouble shooting
- Spot cooler creates lots of dew condensation [5]
- Configuration of register 10 of BP fails often. If 10 MHz clock is not seen, one should configure again manually this register. -> This was because of hexadecial - decimal confusion. Input card of ClusCo should be in decimal. (10 instead of A!).
- If we inject a long pulse (>500 ns) to TIB for software trigger, TIB creates two trigger pulses. This is not expected because TIB enters busy mode at the rising edge of long pulse. Luis Angel is working on this issue. [6]
- (Probably) compressor of spot cooler create a big noise (either on GND or via EM wave) which disturb the clock. If clock is missed, TIB enters the stand-by state, which is very annoying.
- 7th PMT at the central module seems to be delayed so long that it creates 2nd L1 trigger from one light pulse. Maybe L0 delay should be adjusted.
- When data taking of Dragon finishes, TIB becomes busy state. To reset it, we have to reset the TIB.
- If you observe too slow or lost communication with Dragon, it could be due to incomplete SiTCP parameters. To solve the problem, see here Seeting SiTCP Paremeter By Hand. The reason why it happens is unclear.
- If you need to disassemble a module, please see here [7]
- Linearity plot shows strange points at Low gain channels for low intensities. This is caused by DRS4 fundamental pedestal. Some studies were made and results are sammerized here [8] . But we don't fully understand the cause. More studies are needed.
To do lists
- Check PACTA ID of 26 PMTs.
- Change IP of the some Japanese dragons.
