The load for BF was roughly adjusted. The F1, F3, BF are working. The F0 overloads by 13kg. * Started the setup of F1 in EY. === TypeB === === TypeBp === ==== PR3 ==== Given the fact that the gluing of the wire underneath the mirror didn't fix the problem of the stability of the mirror, we decided to tighten the wire clamps. * We locked the payload. * Removed H1 and H2 OSEM flsags with long and narrow pliers. * Removed the side panels. * Tighetened the screws of the weight-holding wires to 10 Nm * Tighetened the screws of the RM locating wire screws to 2 Nm. They rotated beytween 45 degrees and 95 degrees. (The screw heads for the mirror wires are not accesible). * After reassembly we tested pitch stabiliry with the Trupm procedure. * The mirror pitch changed by -5.8 mrad (oplev). * The IM pitch changed by 1. 04 mrad (V2 and V3 OSEMs). * Given this result we want to apply adhesive to the wires at the bottom of the clamps: see slides. === TypeC === === Electronics === === Control === == Safety == == Discussion == == Travel Plans == The week from 3/22 * Takahashi: 3/22-3/26 * Sato: 3/22-3/26 * Hirata: 3/22-3/26 * Yano: 3/22-3/26 The week from 3/29 * Takahashi: 3/29-4/2 * Sato: 3/29-4/2 * Hirata: 3/29-4/2 * Yano: 3/29-4/2 == Next meeting == * 2021/3/26(FRI)
