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.
