The LVDT has a good sensitivity. * It was not possible to carry out the calculation for SR2 due to the poor sensitivity of the LVDT. * Last week, I calculated the intercalibration factor for the BS F0 LVDT, using information of two peaks only (out of three). I'm still on the process of figuring out if this is reliable. === Type-Bp === === Type-C === * Measured the transfer functions of the OMMT1/2/OSTM suspensions after the evacuation. They looked healthy. === Electronics === === Control === == Schedule == * Type-A: Test of ACCs. * Type-B: Use Terrence's methods to tune SR3 F0 and IP; check whether it's possible to do LVDT sensor correction in SRM F0. * Type-Bp: Check whether it's possible to do LVDT sensor correction in PR SFs. * Type-C: == Safety == == Discussion == == Travel Plans == (Date in Kamioka) The week from 12/5 * Takahashi: 12/8-9 * Hirata: 12/6-9 The week from 12/12 == Next meeting == * 2022/12/9(FRI) 13:30
