The performance was worse than the prediction. === Type-B === * We build a new windshield for the BS oplev. * In SR2, the seismometer on ground was calibrated with respect to the IP LVDTs and geophones. * In SR2, the sensor correction filter Terrence designed for SRM was copied to SRM filter banks for temporary usage. * In BS, a leak was found in an electrical feedthrough, we disconnected the cables to facilitate this work. === Type-Bp === === Type-C === * Took photos of the EQ stoppers and the damping magnets in the IMMT suspensions. * Recovered the touching points in the OMMT/OSTM suspensions. === Electronics === === Control === == Schedule == * Type-A: * Type-B: * Type-Bp: Monitoring of the PRM. * Type-C: Final check of the OMMT/OSTM suspensions. == Safety == * Regulation to use the clean booth will be changed. == Discussion == == Travel Plans == (Date in Kamioka) The week from 10/3 * Takahashi: 10/3-7 * Hirata: 10/4-7 * Aso: 10/3-6 The week from 10/10 * Takahashi: * Sato: * Hirata: == Next meeting == * 2022/10/7(FRI)
