== KAGRA Commissioning status at DET meeting ==

 * Date : 2022/08/22

=== Overall schedule ===

 * Overall schedule
  * 7/11 - 8/19 Suspension commissioning Type-B
  * 8/22 - 8/26 Closing the center area PRM~PR2
  * 8/29 - 9/5 Closing the center area BS~SRM
  * 9/6 - pumping down
  * 8/5 Acceptance check PRM, PR2, PR3 suspensions 
  * 8/19 Acceptance check BS, SR2, SR3, SRM
  * 8/22 Acceptance check mid-size baffules
  * 8/26 Acceptance check interferometer

  * Y/YY Acceptance check IMC~PRM

=== Progress of commissioning ===

 * X arm commissioning
  * End X IM 81K
  * Investigation of the noise in the new oplev light source
  * Investigation of the ADC noise

 * Y arm commissioning
  * Pumping down ongoing
  * Installed the ion pums to IXC and IYC
  * IY duct shield cooling (8/5- Started)

 * Beam dump around IFI
  * Many ghost beam
  * beam dumper from reflection beam of the PRM
  * Temperature monitor

 * ALS CARM/DARM
  * ALS CARM/DARM lock succeeded
  * Calibration confirmation
  * Transfer function measurement Type-A suspension
  * Noise budget
  * Now the noise level is limited by the ALS after fiber noise cancellation

 * Find IR resonance improved

 * MICH 3f lock
  * Actuation efficiency measurement
 
 * TCam analysis
  * Find the beam position [[https://klog.icrr.u-tokyo.ac.jp/osl/?r=21839|klog#21839]]

 * OMC alignment


 * Discussion of closing center area
  * Oplev pylon
  * Beam duct re-installation
  * New gate valve
  * Closing chambers around BS area

=== 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
  * MICH 3f lock
   * Check the lock information

  * ALS CARM/DARM
   * Check the lock information

  * 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
