PR2,3,BS,SRM,SR2,SR3 Cleaning(Aso-kun, Hirata-san)

PR2: Acceptable after FCing

PR3: Slight dots could not be removed by even pure water. We accepted this situation.

No cleaning for BS, SRM, SR2, SR3

  • Did you eyeballs checks during the beam path check?

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

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)

Open the GV between SRM-SR3, and Close the GV between SRM-OMC !!

  • tierod adjustment for the GV on the SRM side.

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

  • PR3, PR3, BS :
  • SR2, SR3, SRM : 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.
