| ==== Report for week of 1/29 ==== * We moved the top filter intended for SR2 (#1) into the SR3 cleanbooth. * Unfortunately we noticed one of the blades had many small X-shaped stress fractures on the top surface (klog [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=4058|4058]]). * We moved the top filter entered for SR3 (#3) into the SRM cleanbooth and inspected the blades. Two had one smallish stress fracture each and one had a huge fracture and looks close to failing (klog [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=4061|4061]]). * We referred the BS OL. * We removed the BS tank lid and inspected the BS top filter blades. They seemed fine (klog [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=4073|4073]]). * Hirata-san received and washed some ferromagnetic disks for IM flags and other small parts. * Hirata-san moved the BF with the tilted keystone (#1) out of the cleanbooth in preparation for rebuilding. * Hirata-san placed the second order for payload parts, and an order for remachining of nuts for cable clamps on rods. * Fabian measured the gain of the ADC system (homework from the Commissioning Workshop). ==== Plan for week of 2/5 ==== * Enzo on vacation; all others at Kamioka. * - * Make in-air pico adapter cables. * Calibrate LVDT. * Test IM picos and BF yaw pico. * Test FR. * Install ballast mass in BF. * Build IRM around IM. * Cable/test/adjust IM OSEMs. * Time permitting, do TFs from IM OSEMs to themselves and to optical sensor. |

Report for week of 4/2
- Fujii-kun and Yamamoto-kun got the SR3 real time model running.
- We received the SR3.
- However Mark and Tanioka-kun found Hirose-san had applied the First Contact patterns on the wrong sides, so we took it to Yamamoto-san's lab and Toyama University and re-applied the FC properly. We also bounced a 1064 nm beam off it to verify that the HR and AR coatings were not also swapped (they were OK).
- We made magnet-standoff assemblies for both SR3 and SRM, and set up for gluing the prisms and magnets. We will attach the prisms and magnet-standoffs on Monday.
- Hirata-san did inventory of the SR3/SRM payload parts received last week and started on the inventory of screws.
- Fujii-kun, Enzo and team finished the preparation, adjustment of the SFs and BFs.
- They calibrated one SF and BF. (The remaining one SF and BF will take about another day. Also, the FR stops need to be checked.)
