* '''Type-Bp Schedule''' When will we do the recovering work for type-Bp suspensions? Fabian team go to X end in next week even we could not complete the upgrade work on 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? * |

PR3 Summary:
Type-Bp
- After the release of the jammed picomotor, Ikeda-san moved back the sliding mass but he was unable to recover the same orientation of the IM according to the OSEMs. Pitch and were ended up with different values.
- The transfer functions showed an unhealthy system.
- Before doing visual inspection of the IM I moved IM-Y to zero from 1.78 mrad. However, while opening the chamber (cloth covers) it moved to about -500 urad. Moreover, during subsequent work it went to -2.3 mrad and it's been stable there.
- A few OSEM flags seem to be touching the OSEM bodies. Their positions are consistent with the large amount of yaw measured.
- About cables:
- Cables from the IM touch cables from the IM. (Lilkely not good but not too bad.)
- Cables from the IRM touch cables from the IRM. (Lilkely not good but not too bad.)
- A cable from the BF is touching the BF Damper.
- A cable from the BF Damper is touching the security structure before it's clamping point on the security structure.
- We provided more slack to those cables by improvising a additional clamping point on the securuty structure. This might have improved the situation of H1 OSEM flag but it did not solve the overall problem.
- There are some cables which are dangerously close to touching other cables.
- Today we assesed again the position of the OSEM flags.
- What do do?
- Maybe we should move the BF picomotor again.
- Adjust the tilt of BF by putting temporary ballast masses (in places yet to be decided) to see if the IM is released.
- Move OSEM panels?
