The controls were successful. The noise spectra of the geophones became worse at frequencies higher than 1Hz. * We plan to test with the HPCs in EX and EY to compare. === Type-B === === Type-Bp === * Ushiba-san measured TF from the seismometer on ground and the BF Damper in longitudinal. * The calculation of the inter-calibration factor between the seismometer and the BF Damper LVDT is ongoing. There's no result yet. === Type-C === === Electronics === === Control === == Schedule == * Type-A: IP control with ACCs. * Type-B/Bp: Vertical sensor correction. * Type-C: Monitoring of the OMMT1/2/OSTM suspensions. == Safety == == Discussion == == Travel Plans == (Date in Kamioka) The week from 1/30 * Fabian will be away on Friday 3rd of February. == Next meeting == * 2023/2/3(FRI) 13:30-
