Progress report
General
Type-A
Type-B
- Fabian analyzed data of the SR2 suspension decay times with the control system on. Almost done but no plot to show yet.
On Thursday I helped Ushiba-san and Yokozawa-san to measure the BS oplev QPDs dark noise. See klog entry 14473.
- No questions about inertial damping today.
Type-Bp
Type-C
Controls
- Type-A modeling (Shoda)
- (for the paper) Searching for the fastest way to derive the theoretical spring constant of the actual HLs.
- (for the cryo-p evaluation) The RT model is updated. Need update of the actuation efficiency.
Electronics
Post O3
- More activities in the control room and the site became available from June 1st (Noise budget measurement by Ushiba).
- O3c has not been decided yet, but the situation is going to O4 directly.
- The site work towards O4 is rescheduled. The extended chief meeting will be held on June 15th to discuss about the plan towards O4.
Post Obs. task (Request), Task for O3c (Plan, Sheet).
