Health check. ADC noise. Go to implementation of SI. * EY: Finalization. Health check. ADC noise. BF LVDT noise. Cabling repair (P7-2). Go to implementation of SI. * Type-B: Calibration of geophone in SR2. Stand-alone SM driver for SR3. * Type-Bp: FC onto PRM (small regidual FC on AR). Traverser limit SW: Installation in PRM in the early next week. MSB: Installation in PRM in the late next week. FC onto PR3 on 5/23. * Type-C: OMC installation from 5/23. Health check of OMMT1/2/OSTM. == Status == * Replacement of flip cables: Replaced for TMS in EY. * TM height setting: * Oplev: Windshield in the next. * ACC: * Commissioning in air: * Commissioning in vacuum: * Acceptance check: Review from 5/13. * PF actuator: At the in-vacuum commissioning. * New vacuum pumps for V-chambers: How to treat thermal load? * Heater control: Pending. * TMS: Thermometer * Cryo-shield: Finnese measurement, height check --> Cooler ON. == Discussion == ---------- = VIS Meeting = Date: 2022/5/13 14:00-14:40 Participants: Takahashi, Ushiba, Fabian, Aso, Tanaka, Washimi == Summary Report == === Type-A === * Replaced the main card of the LVDT driver for the BF damper in EY. * Repaired the cabling for the thermometer in EY. * Closed four feedthrough flanges in EY and two ones in IY. * Replaced the HPCD for the IP in IY === Type-B === I kept working on the geophones calibration transfer functions. See slides. === Type-Bp === We applied FC to PRM. === Type-C === * Measured the transfer functions of suspensions for OMMT1, OMMT2, and OSTM. Adjusted the position of H2 OSEMs for OMMT2/OSTM, and H4 OSEM for OMMT2. The baffle plates on the suspension frames were removed temporally, and they were returned back. === Electronics === === Control === == Schedule == See [[http://gwwiki.icrr.u-tokyo.ac.jp/JGWwiki/KAGRA/Subgroups/VIS/Schedule|Schedule]] * Type-A: Review of IY and EY. * Type-B/Bp/C: Installation of traverse limit switches and MSB in PRM. Calibration of the geophones in SR2. == Safety == == Discussion == == Travel Plans == (Date in Kamioka) The week from 5/16 * Takahashi: 5/17-20 * Sato: 5/16-20 * Hirata: 5/17-20 The week from 5/9 * Takahashi: 5/9-13 * Sato: 5/9-13 * Hirata: 5/9-13 == Next meeting == * 2022/5/20(FRI)
