Offload in IX and EX. Elena-san will try to damp ITMX. * Type-B: Measurement on the sensor correction in SR2. * Type-Bp: Test of damping control. * Type-C: == Other items == * Oplev: Check of TM Oplev in EX. * ACC: * Commissioning: * Vacuum system: Waiting for the GV opening in EX. * Heater control: * TMS: == Post O4a == * Measurements of the DAC noise: Type-C. * Measurements on the sensor correction in SR2: Performed by Terrence on 9/12. * Optimization of the damping control in PRs: Tested for PR3 and PRM on 9/12. * IP control with the ACCs: One more test is necessary. * In-vacuum accelerometer for IOO: Leak test of the pod is planned in early October. * Hight adjustments of Type-A in the cooling: Monitoring from 9/8. * Temperature control for the Oplev: Prepare for IXC and EXC. * TM cooling: Schedule. * IM heater: Setup for IX and EY was finished. * OMC damper: The parts should be prepared by 9/13. == Discussion == ---------- = VIS Meeting = Date: 2023/9/22 10:00-10:45 Participants: Takahashi, Tanaka, Sato, Ushiba, Hirata, Mitsuhashi == Summary Report == === Type-A === * Height adjustment of ETMX. === Type-B === * Measurement on the sensor correction in SR2 by Terrence. === Type-Bp === * Optimization of damping controls for PR3 and PRM. The behavior of angular fluctuation should be checked as well in PR3. === Type-C === * Damping of the OMC suspension. * Production of the blade damper. * Prototype test of the flexible pendulum damper. === Electronics === === Control === === R&D === * TAMA-SAS experiment: TF measurement of IP+RL. == Schedule == * TAMA-SAS experiment. * Finalization of the OMC damper. == Toward O5 == * [[https://paper.dropbox.com/doc/VIS-upgrade-toward-O5--B6qw57_1ZTHOEO_ZdAZi0hBjAQ-PJElGnRfe5jbNPeHWDHzi|Dropbox paper]] == Discussion == == Next meeting == * 2023/9/29 10:00-
