==== 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.

Summary Report

TypeA

  • Connected the cryo-payload to the BF in EX. 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.
