PR3

https://klog.icrr.u-tokyo.ac.jp/osl/?r=29520

No cleaning for BS, SRM, SR2, SR3

Did you eyeballs check during the beam path check?

Suspension Condition of PR2, PR3, BS, SR3, SR2, SRM. (Takahashi-san, Ushiba-kun, Hirata-san)

- Isolation of Wiring from coils to flanges(pico and mag-coil) ->
- Cable repair for the BF damper. The lead wires were glued to prevent direct touching of the wires to the coil bobbins.
- Fixing the cable connector for SF LVDT
OSEM conditions
Smooth Mag-coil motion and balance and TFs
Spectrum

Mirror conditions(??)
- Clean around the center?

Oplev Check for PR2,3,BS,SRM,SR2,SR3. (Yokozawa-kun)

Activities:

Beam Power

Beam Path Clearance

QPD centering

Calibration

Spectrum Health

Oplev beam's stray light influence

almost no light?

Oplev table covering

we will do this after closing.

Beam path and Baffle Position

Leaked hermetic flange repair on BS

Vacuum system (Kimura/Uchiyama and their selected persons)

Clean inside as much as possible including the bellows duct with TMP

maybe impossible from the only side hatches.

Check the flange seal surface condition where were opened.

Decide where the elastomer/Metal gasket will be used.

Check the opened flanges and the top hut of PRM2, 3

Logistic to reinstall the bellows duct with TMP.

Sawada-sana and Mirapro members call
If you use chain block, please be careful of its fixing
Careful cramp tightening near oplevs.
