2018-08-21	Reccardo Carlos, Miguel, Tony, Daniel, Shunsuke, Yusuke, Yuji	Module Installation	We installed 98 modules (from column 18 to column 12) to the camera. In total 106 modules were installed. For 89 modules (from column 19 to column 13), we tried to perform sanity and connection test. We were able to ping all modules, then we could read firmware and tempaature for all modules. At first look, L0 and L1 scans went fine, but deeper investigation needed. About Dragon QC, results were fine. However only for 2 modules, Dragon QC has stopped in the middle. for column12, we will perform the test tomorrow. We also found 2 data optical fibers through which we could not communicate with the modules, we used the one spare optical fiber we have and we replaced the second one with the optical fiber for the UCTS.	https://drive.google.com/open?id=1DdRUGOgVrMz2Pivtg7P4Zre2Va-aYO1C
2018-08-20	Shunsuke	Brief check of Mezzanine	checked sanity of the Mezzanine for 3 rack = 57 modules and more. I found 9 more mezzanine missing parts. In 9 mezzanines, some strange mezzanine found. It was L0 ASIC not covered by material, missing parts and fixed without parts? And a small parts was soldered with strange angle. See pictures.	https://drive.google.com/open?id=1G_3LFysZG-ia6awGCnLEbGedMsC1UVvI
2018-08-20	Carlos, Daniel, Shunsuke	Test of the traveling modules	1-58 and C008.140_02 were transported from IFAE in the camera. So we checked the effect of travel. We did L0 rate scan, L1 rate scan with test pulse and Backplane resistor reading. Daniel and Shunsuke confirmed a consistency of result of the test to one took in IFAE. These were fine. But one of the mezzanine's pin was bend. It means the bend pin does not effect with communication.	https://drive.google.com/open?id=1jBe10SAx17wu7F7rRw-qSGyjg6ZwLde7
2018-08-20	Reccardo Carlos, Miguel, Tony, Daniel, Shunsuke, Yusuke, Yuji	Module Installation for Column 19th	We started install modules to camera, with confirming procedures one by one. Procedures start from powering on generator, power supply, camera, and modules proceed to preparing of PMT modules. Then we discussed about procedures, we check again tomorrow. Today we finished to install 1st column (col19th), without some tests for checking communications.	https://drive.google.com/open?id=1DdRUGOgVrMz2Pivtg7P4Zre2Va-aYO1C
2018-08-20	Yusuke, Yuji	LG assembly	Assembled 59 modules. In total 268 modules were assembled. last 2 modules will not be installed to camera. So these were not assembled. Basically, this work has done.
2018-08-17	Daniel, Shunsuke	Dragon QC for checking Dragon	For checking a sanity of Dragon board, I tried to perform Dragon QC by my PC. But it was failure. So I connected Dragon (2-128) to Osaka directly (through em3), execute QCDaq.sh. It was performed fine. It has not analysed yet.	https://drive.google.com/open?id=1qZn6j4hAUSn2enz7DvvBQ3rBdhGzwVOd
2018-08-17	Carlos, Miguel, Tony, Daniel, Shunsuke	Camera opening	Carlos, Miguel and Tony were arrived. We have cleaned up around the camera. After that, they removed materials from a camera transport structure. We can access the both side of the camera now.	https://drive.google.com/open?id=1jBe10SAx17wu7F7rRw-qSGyjg6ZwLde7
2018-08-17	Toko, Daniel, Yusuke, Shunsuke, Yuji	Assembly LG to PMT module	assembled 76 modules. 2 or 3 mezzanines had a problem in each racks, and we found that missing a capacitor and an inductor on Mezzanine. This may be a pretty problem. Those parts should be soldered. In total 209 modules were assembled. And Al plates for transportation were all removed from modules. So we can attach a new LG to the module immediately.	https://drive.google.com/open?id=1nQkuRGRz-w8eayIwtCO98NLbOyxmQN4Y
2018-08-16	Toko, Daniel, Yusuke, Shunsuke, Yuji	Assembly LG to PMT module	assembled 76 modules. This corresponds to four module racks. 2 or 3 mezzanines had a problem in each racks, these problems have fixed by Daniel. In total 133 modules were assembled.
2018-08-15	Toko, Daniel, Yusuke, Shunsuke, Yuji	Assembly LG to PMT module	assembled 52 modules. 11 mezzanines has pins problems. After Daniel was arrived in Mirca, these problems have fixed by him. The modules were covered by plastic bag. The pictures are in the following web.	https://drive.google.com/open?id=1nNdVpm95B9fIDlFu7MplnQDmV4I2afrc
2018-08-14	Toko, Yusuke, Shunsuke, Yuji	Assembly LG to PMT module	assembled new LG for 5 modules. during that works, we found 2 problematic things. At first, scree for fixing modules to module molder was fall out. (see the link.) and another, broken connectors of the mezzanine. some pins bend like pictures. we checked about 20 modules, problems were found in 5 modules.	https://drive.google.com/open?id=1nNdVpm95B9fIDlFu7MplnQDmV4I2afrc
2018-08-14	Toko, Yusuke, Shunsuke, Yuji	Picking up Mr. Yamamoto	also went to buy a staff for LG assembly. Alcohol for wiping cathode plane.
2018-08-14	Yusuke, Shunsuke, Yuji	Preparation for Light Guide assembly	Opened transportation boxes of LG, and moved them in the clean room.
2018-08-14	Yusuke, Shunsuke, Yuji	Building a Big Black Box	Assembled side panels to flames of the dark box, 50 % panels were assembled until now.
2018-08-13	Yusuke, Shunsuke, Yuji	Shopping staffs for Light Guide assembly	went to buy the materials for a clean room, It will be used in LG assembly. Staffs are, e.g., table, chairs, and clean suits.
2018-08-13	Yusuke, Shunsuke, Yuji	Building a Big Black Box	Assembled the black box which used in IAC for module QC. We finished almost whole part of frames, but we need additional screws for it.
2018-08-13	Yusuke, Shunsuke, Yuji	Unpacking of transportation boxes for PMT modules	PMT modules have delivered to Mirca by wooden boxes, and it was fixed by screws. We finished dismounting these screws from boxes. we can use all modules without another preparation.
2018-08-08	Patrcia Marquez	Camera, chiller and the modules arrived in Mirca
