Safety
Discussion
When will we do the recovering work for type-Bp suspensions? Situations of the suspension are here;
- PRM: All cables are connected except the PSD which is not use now. Miyo is checking the acceptance items; TF of the plant response, sensor noise level, calibration values, diagonalization, coil balancing, damping filter.
- PR2: Cables connected but signal is not coming from the satelite box. We have to check. I can do that next week with Nakagaki-san even I have to join the IMC commissioning.
- PR3: All Cables are connected. Fabian team is investigating the suspension which is touching somewhere.
Cabling style of the thermistors is reviewed by SEO?
- How to extract the thermistor cables?
- No conflict to other subsystems: AOS VAC? Stray light is OK? The cabling does not disturb VAC people to work when they install the bellows?
