Outgassing from the pod should be checked independently. * Hight adjustments of Type-A in the cooling: [[https://paper.dropbox.com/doc/Hight-adjustment-in-cooling--B7ii3omB81JIm6khnBt_7fcaAQ-swWQ5h6M6lSs8yLp5D6dA|The procedure]]. Cooling will be started in EX on 7/27. * Noise budget of the suspensions: * Temperature control for the Oplev: Preparing for the heater controller. The power controllers were delivered. == Discussion == ---------- = VIS Meeting = Date: 2023/7/21 10:00-11:00 Participants: Takahashi, Aso, Mitsuhashi, Sato, Hirata, Tanaka == Summary Report == === Type-A === * Height adjustment toward the cooling. === Type-B === === Type-Bp === === Type-C === * Damping of the OMC suspension. * Prototype test of the blade damper. * Design of the flexible pendulum damper. === Electronics === === Control === === R&D === * Moved the TAMA-SAS tower from the warehouse to the ATC lab on 7/20. == Schedule == * Monitoring and offload of Type-A during the cooling. == Toward O5 == * [[https://paper.dropbox.com/doc/VIS-upgrade-toward-O5--B6qw57_1ZTHOEO_ZdAZi0hBjAQ-PJElGnRfe5jbNPeHWDHzi|Dropbox paper]] == Discussion == == Next meeting == * 2023/8/4 10:30-
