The setpoints of F1 and F3 were changed ([[https://klog.icrr.u-tokyo.ac.jp/osl/?r=35544|klog]]). * Height adjustment * Warming up will start on Dec. 8. * ACCs for the IP controls. * TF measurements of the folded pendulum are planned. * Preparing for three ACCs. === Type-B/Bp === * IRM damper for Type-B. * Installation in SRM is scheduled on 3/9-19. * Enclosure for the SG card in an independent box. * Preparing for the boxes with a 1U rack panel. * IP for Type-Bp. * Started a design. === Type-C === * Active isolation table for OMC. * The new geophone pod is assembled. A leak test should be performed. * The effect due to the evacuation of the TMS chamber was small (<20um). The effect due to the temperature change was larger. * Sato-san is designing the fishing rod (FR). FRs will be useful for the initial adjustment. * Small Type-C suspensions with mini-GAS. === R&D === == Discussion == * The modification of the Type-A tower toward O6. == Next meeting == * 2025/12/5 10:00-
