It was determined that the problem was deep within the chamber, and we cannot fix it from outside. The yaw picomotor should still be functional because such a pin is connected to ground at the driver. * In SR suspensions, we withdrew security stop screws to allow larger motion of the whole suspension in the longitudinal direction by approximately 5 mm. Clearly, we didn't move the stop screws around the F1 filters. * We installed dial gauges in all four Type-B chambers underneath the mushroom heads. The aim is to monitor the motion of the chamber when pump down happens. * Yokozawa-san took pictures of the inside of the chambers with the 360 degrees (4pi sr) camera. === Type-Bp === === Type-C === * It is planned to shift the OMMT2 suspension to Y+ by ~20cm for the mode matching. === Electronics === === Control === == Schedule == * Type-A: * Type-B: Monitor of the evacuation. * Type-Bp: Monitor of the evacuation. * Type-C: == Safety == == Discussion == == Travel Plans == (Date in Kamioka) The week from 9/5 * Takahashi: 9/6-9 * Sato: * Hirata: 9/5-9/9 The week from 9/12 * Takahashi: * Sato: * Hirata: == Next meeting == * 2022/9/9(FRI)
