Trouble of stepper motors in EY. Update of MN OL damp in IY. * Type-B: * Type-Bp: Check of PRM suspension control. * Type-C: == Other items == * Oplev: * ACC: * Commissioning: * Vacuum system: GV control by not MDEM but SwitchBot. Automation using additional vacuum gauges. * Heater control: Changed the setpoint in IY. * TMS: == Post O4a == * Measurements of the DAC noise: Type-C. * Optimization of the damping control in PRs: PR3. * IP control with the ACCs: One more test. * In-vacuum accelerometer for IOO: Preparing the geophone pod for IFI chamber. Ag coat screw with ditch is necessary. * Height adjustments of Type-A in the cooling: Continued. == Discussion == ---------- = VIS Meeting = Date: 2023/11/10 10:00-12:00 Participants: Mitsuhashi, Aso, Takahashi, Sato, Hirata, Tanaka, Tomaru, Otsuka == Summary Report == === Type-A === * Height adjustment of ETMX and ETMY. * Trouble of the stepper motors in EY. === Type-B === === Type-Bp === === Type-C === === Electronics === === Control === === R&D === * TAMA-SAS experiment: Measurement of RL resonances. * Calculation of the RL potential. == Schedule == * TAMA-SAS experiment. == Toward O5 == [[https://paper.dropbox.com/doc/VIS-upgrade-toward-O5--B6qw57_1ZTHOEO_ZdAZi0hBjAQ-PJElGnRfe5jbNPeHWDHzi|Dropbox paper]] * Design and test of the mini-GAS for the KFC suspension. == Discussion == == Next meeting == * 2023/11/24 10:00-
