Agenda/Minutes of the VIS Meeting on 2020/6/5
2020/6/5 14:00 -
Participants: Takahashi, Fabian, Sato, Hirata, Aso, Shoda, Lucia, Ishizaki, Tanaka, Miyo
Progress report
General
Because of Nakano-san and Miyoki-san's request, Miyo made VIS_MANAGER guardian to monitor and manage all suspensions. klog14469
- Now, this guardian requests the all suspensions to go PAY_LOCAL_DAMPED state for safety when an earthquake hits.
- but, there are no big earthquakes from this work. When big earthquakes happen, I will check and modify this guardian.
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
- Started measurements of the circuits. It takes much time due to many variations of inductor.
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.
- Tasks on electronics should be combined to the task list towards O4.
- Procedure of the wire gluing should be confirmed beforehand.
- Schedule including the commissioning should be considered, but overall plan and schedule, which will be discussed in the next SEO/Chief meeting, are necessary to make detail schedule.
