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
2017-2-20	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.
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.

- TIB [3]

- BP [4]

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.
