Summary Report
Type-A
- Offloaded the BF GAS in IY.
Type-B
I posted plots comparing BS and SR2 TFs calculated with the Matlab rigid-body model. See klog 21813
- Review at 15:00 on 19th.
Type-Bp
Type-C
Electronics
Control
Schedule
- Type-A:
- Type-B: Height check. Rubbing check. Adjustment of F1 damper in BS/SR2. Adjustment of F0 FR in BS. Oplev check (various).
- Type-Bp:
- Type-C:
Safety
Discussion
- How to set the F0 FR in BS?
The present temperature is 23.5. Though we can use the heater on the chamber later, we should keep a margine of the cooling power. 23.2 is optimal?
