Offload of the GAS filters. * Type-B: Replacement of the mirror in SRM. * Type-Bp: Adjustment of the OpLev in PR2/PR3. Investigation of the PR2 suspension. Health check in the next week. * Type-C: Health check of the IMMT1/2 in the next week. == Status == * Replacement of cables: EXT and BF temp. * TM height setting: * Oplev: * ACC: * Commissioning in air: * Commissioning in vacuum: Keeping the X-arm. Health check in Y-arm. * Acceptance check: * New vacuum pumps: When should we implement the ion pumps? It is better to do before cooling. * Heater control: Pending. * TMS: == Discussion == ---------- = VIS Meeting = Date: 2022/7/8 14:00-14:15 Participants: Takahashi, Uchiyama, Fabian, Tanaka, Aso, Ushiba, Washimi == Summary Report == === Type-A === * Offloaded the GAS filters after the pump down in EY. * Replaced the cables for BF-FR, BF-TEMP, BF-GAS in EY. === Type-B === * We replaced the small SRM mirror. The process went smoothly. I measured IM transfer functions yesterday, but I haven't compared with older measurements. Klog pending. * With Yokozawa-san, we checked whether the SRM and SR3 oplev beams were reaching the central regions of their respective mirrors. The beam in SR3 is a little lower than expected, but not by too much. === Type-Bp === * Visual inspection of PRs. PR2 only has a small hexagon between the BF and the IM. === Type-C === === Electronics === === Control === == Schedule == * Type-A: * Type-B: Health check. * Type-Bp: Health check. * Type-C: Health check of IMMT1/2. == Safety == == Discussion == == Travel Plans == (Date in Kamioka) The week from 7/11 * Hirata: 7/12-15 The week from 7/18 * Sato: * Hirata: == Next meeting == * 2022/7/15(FRI)
