== KAGRA Commissioning status at DET meeting ==

 * Date : 2022/07/04

=== Overall schedule ===

 * (In case of no trouble)
  * 6/20 - 7/1 Suspension commissioning Type-Bp (Continued)
  * 7/4 - 7/8 Interferometer commissioning (Alignment, Optics characterization, SRM replacement, ...)
  * 7/11 - 7/22 Suspension commissioning 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 (SR3, SRM)
  * SRM replacement (Week of 7/4)
  * ISS installation (Review 7/19)
  * High power laser installation (Week of 7/4)

=== Progress of commissioning ===

 * X arm commissioning
  * End X IM 80K
  * Investigation of the noise in the new oplev light source

 * Y arm commissioning
  * End Y : Pumping down ongoing

 * Center area commissioning  
  * Suspension health check Type-Bp's (Monitor, actuator, cabling)
   * PR2 and PR3 length sensing oplev seems strange, need to check
  * Mirror cleaning SR3 and SRM : Done
  * Investigation of the X-arm fiber noise cancellation
   * Precise alignment better, but not stable 
   * We found the weak point around PR3, Miyoki-san fixed it and became better
   * New PDs are discussed
  * Study for installation of the new laser 
   * Set inside the PSL room this week

=== Interesting data ===

 * X arm cavity
  * Both IR and GR
  * Glitch investigation of the ITMX ADC
  * Glitch investigation of the MN oplev light source

 * Y arm commissioning
  * Both IR and GR

 * Center area commissioning
  * Main IR 
  * ALS
  * IMC (Input Mode Cleaner)
   * ASC (Alignment Sensing and Control) done
   * Long term stability check
    * Beam power, beam position, oplev monitoring
   * Glitch investigation
   * Temperature dependence
   * Relationship between PSL room
   * With PEM channels 
   * (Hammering test?)
  * OMC
   * Invesigation will continue after closing the center area
   * Because the BS is too fluctuate, it became difficult to investigate
