Overall schedule
- 7/4 - 7/8 Interferometer commissioning
- 7/11 - 7/22 Suspension commissioning Type-Bp and Type-B
- 7/25 - 7/29 Acceptance check ~PR2
- 8/1 - 8/5 Closing the center area ~PR2
- 8/8 - 8/19 (Including Obon) Acceptance check ~SRM
- 8/22 - 8/26 Closing the center area ~SRM
- 8/29 - 9/2 Leak test
- Mid size baffle installation partially done (SR3, SRM)
- SRM replacement (Done)
- ISS installation (Review 7/19)
- High power laser installation (Brought to KAGRA site)
Procedure toward X arm commissioning
- Radiation shield cooling Xend
  - IM temperature is ~80 K
  - Finesse is not changed
Y arm commissioning
- EY : Pumping down ongoing
  - Still there are leak 3e-10 Pa level, additional repairing ongoing
- IY : We will start the duct shield cooling, depending on the pressure level and health check
OMC power budget
- After the interferometer alignment and SRM replacement, power budget ongoing
  - The power loss around OMC is one of the important investigation point at O3GK
- Beam profile measurement will be planned next week
TMSX investigation for ASC
- Position of QPD for alignment sensing and control
- Beam shape investigation
Fiber noise cancellation
- Many investigations are ongoing, it became much better
