Offloaded the GAS filters in IX on 7/3. * Type-B: * Type-Bp: * Type-C: == Other items == * Oplev: Check of the length Oplevs. QPD centering is necessary for PRs. * ACC: Test of the IP control with ACCs in IY. * Commissioning: * Vacuum system: Build the OMC chamber up to 1atm. * Heater control: * TMS: == Post O4a == * Measurements of the DAC noise: Every Friday from 7/7. * Measurements on the sensor correction in SR2: 1 night. * Optimization of the damping control in PRs: Measurements 2 days, Test 3 days. Check the SUMCON model. * IP control with the ACCs: Postponed the long-term test in IY. * In-vacuum accelerometer for IOO: Install the geophone pod into the OMC chamber on 7/10. * Hight adjustments of Type-A in the cooling: Confirm [[https://paper.dropbox.com/doc/Hight-adjustment-in-cooling--B7ii3omB81JIm6khnBt_7fcaAQ-swWQ5h6M6lSs8yLp5D6dA|the procedure]]. * Check of the length Oplev: Finished except for IY. * Noise budget of the suspensions: Finished except for the tower part. * Temperature control for the Oplev: Preparing for the heater controller. == Discussion == ---------- = VIS Meeting = Date: 2023/7/7 10:00-10:25 Participants: Takahashi, Mitsuhashi, Tanaka, Aso == Summary Report == === Type-A === * Test of the IP control with ACCs was postponed in IY. === Type-B === === Type-Bp === === Type-C === * Damping of the OMC suspension. * Design of the blade damper. * Design of the flexible pendulum damper. === Electronics === === Control === === R&D === * Table-top experiment of the Roberts Linkage. * Measured the TF of each direction X/Y. Each resonant frequency was identified. == Schedule == * Installation of the geophone pod into the OMC chamber on 7/10. * Move the TAMA-SAS tower from the warehouse to the ATC lab on 7/19. == Toward O5 == * [[https://paper.dropbox.com/doc/VIS-upgrade-toward-O5--B6qw57_1ZTHOEO_ZdAZi0hBjAQ-PJElGnRfe5jbNPeHWDHzi|Dropbox paper]] == Discussion == == Next meeting == * 2023/7/21 10:00-
