| 2017-3-10 | Yusuke | Assembly | Assembled 12 Modules (in total 62 modules) | ||
| 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 : https://drive.google.com/open?id=0B6V4naKAxXfUcEMzSF95bjlGTkk https://drive.google.com/open?id=0B6V4naKAxXfUT1RZcmpuU0tKbjg https://drive.google.com/open?id=0B6V4naKAxXfUN1RDRnc2WDlHc0U | |
| 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 | |
| 2017-3-7 | Yusuke | Assembly | Yusuke assembled 28 Modules | ||

| 2017-3-6 | Shunsuke, Seiya and Yusuke | Documentation, Knowledge transfer | Shunsuke started to document things. | Schematic diagram of the system. https://drive.google.com/open?id=0B6V4naKAxXfUUWxfeEVZd1RRZHM | |
| 2017-3-6 | Daisuke, Shunsuke, Seiya and Yusuke | QC | All necessary data are taken (except for those with NSB). We will re-analyse data with Takayuki's program tomorrow. | ||
| 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. |

| 2017-2-28 | Andrea, Daisuke, Shunsuke, Seiya and Yusuke | QC | We worked only during the morning today. Attached are the single phe distribution, HV vs Gain data. Analysis software need some minor optimisation. 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. | ||
| 2017-2-02 | Shu, Shunsuke, Taka, Yusuke | Holiday | Official Holiday in Canary Island. | ||
| 2017-2-01 | Shu, Shunsuke, Taka, Yusuke | Analog sum propagation study | We tried to understand the correspondence between geometry of neighboring modules and L1 ASIC inputs. It was complicated but we manage to understand it by applying HV to one module and check triggers in the neighboring modules with no HV. | https://drive.google.com/open?id=0B6V4naKAxXfUaFRLbnJTZG5QUHM https://drive.google.com/open?id=0B6V4naKAxXfUeHBjQ3JOVzFlSW8 | |

| 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 | |
| 2017-1-23 | Shu, Shunsuke, Taka, Yusuke | Cabling | We connected the 380 V from the wall to PSU and got 24 V for the first time. It is working fine. QC measurements on 1 Italian Dragon was performed, finding no problem. Air pipe from the spot cooler is still an issue. | ||
| 2017-1-23 | Shu, Shunsuke, Taka, Yusuke | Module Assembly | We sorted 500 PMTs according to QE. We put LOCTITE to screws between PACTA and PMTs for 100 PMTs. | ||
| 2017-1-20 | Shu, Shunsuke, Taka, Yusuke | Module Assembly | We have built 19 PMT heads and 13 Dragon bodies so far. We cannot build more because "spacers" and SCBs are missing. | ||
| 2017-1-19 | Shu, Shunsuke, Taka, Yusuke | Module Assembly | We built 9 PMT heads (PMT + tubes + SCB) and 5 Dragon bodies (Dragon + frame). | ||
| 2017-1-18 | Shu, Shunsuke, Taka, Yusuke | Module Assembly | Yusuke instructed Shu, Shunsuke and Taka how to put the aluminum frame on Dragon. Now all of us can do that. | ||
| 2017-1-18 | Shu, Shunsuke, Taka, Yusuke | Cabling | We managed to buy the 15m 380 V cable at Coelca suggested by Javier. The connector was mounted by Sergio. | ||

| 2017-1-16 | Shu, Shunsuke, Taka, Yusuke | Cabling | We need 380 V input for the power supply. It can be provided by the wall of the clean room but the outlet is 15 m away. Such cable was not in IAC. We went to the electric shop El Faro, but they had only connectors. | ||
| 2017-1-16 | Shu, Shunsuke, Taka, Yusuke | Construct Dark Box | We bought black tapes in El Faro suggested by Juan Calvo and taping at all edges are done. However, we faced a slight shortage of sponge to fill the connection gaps between two half boxes. | ||
| 2017-1-13 | Yusuke | Module Assembly | We checked if the positions of holes etc of Italian Dragon are fine. We found no problem. | https://drive.google.com/open?id=0B6V4naKAxXfUSjRSQ3Z5LXM0WWs | |
| 2017-1-13 | Shu, Shunsuke, Taka, Yusuke | Construct Dark Box | 90% are done. We had to stop because we ran out of black tapes. We didn't find one in the city. Mirror adjustment is also not yet done. | ||

- 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.
