Takahashi-san gave me the information about calibration factors, but I still have to take a look at it. === Type-Bp === * We installed new cable clamps and limit switches in PR3. * We locked the suspension for First Contact application. === Type-C === * Recovered the IM touching the magnets in OMMT2 suspension. * Performed the health check of OMMT1, OMMT2, and OSTM after the OMC alignment. It is necessary to adjust the H3 OSEM in OMMT1. === Electronics === === Control === == Schedule == * Type-A: * Type-B: Stand-alone SM driver for SR3, Geophone work in SR2. * Type-Bp: MSB on PR3. Traverser limit SW in PR2. * Type-C: == Safety == == Discussion == == Travel Plans == (Date in Kamioka) The week from 6/13 * Takahashi: 6/14-17 * Sato: 6/14-17 * Hirata: 6/14-17 The week from 6/20 * Takahashi: * Sato: * Hirata: == Next meeting == * 2022/6/17(FRI)
