Improvement of the controls. * Type-B: Monitoring of the evacuation. * Type-Bp: Recovery of the BF GAS in PR3. Monitoring of the evacuation. Centering of the oplev in PR2. * Type-C: Health check of the IMMT suspensions. Shift of the OMMT2 suspension in the next week. == Status == * Replacement of cables: EXT remains. * TM height setting: * Oplev: Windshield in PR2. * ACC: * Commissioning in air: * Commissioning in vacuum: MICH and FPMI Lock. * Acceptance check: [[https://paper.dropbox.com/folder/show/AcceptanceTest-e.1gg8YzoPEhbTkrhvQwJ2zzo3dHVh5sJGieDgbm2n3h60mGqotBeE|DropboxPaper]] * Vacuum system: Pump down of the center area from 9/13. Large leak in PR3-PRM and SR3-SRM. * Heater control: Pending. * TMS: == Discussion == ---------- = VIS Meeting = Date: 2022/9/16 14:00- Participants: Takahashi, Fabian, Ushiba, Tanaka, Miyoki, Washimi, Aso == Summary Report == === Type-A === [Washimi] * The effects due to walking around IXV area were investigated. The seismometer signal drifted by walking at the wall side near the seismometer. === Type-B === * We monitored the IPs during air evacuation from the chambers. * I calculated the values of the buoyancy effect. * I moved all GAS filters and IPs close to their setpoints. === Type-Bp === * The GAS filters were monitored during evacuation, although there were not compensated as often as IPs. === Type-C === * Health checks of the IMMT suspensions are ongoing. DC gain of TFs in IMMT1 is larger than IMMT2 by 3-4dB. === Electronics === === Control === == Schedule == * Type-A: * Type-B: Oplev work. * Type-Bp: * Type-C: Shift of the OMMT2 suspension (depending on the GV status). Final check of the IMMT suspensions. == Safety == == Discussion == == Travel Plans == (Date in Kamioka) The week from 9/19 * Takahashi: 9/20-22 * Aso: 9/20-22 * Fabian will be on holidays. The week from 9/26 * Takahashi: * Sato: * Hirata: == Next meeting == * 2022/9/30(FRI)
