==== Business travel ====

 * Depending on the situation of COVID-19
 * To Kamioka
  * No
 * From Kamioka
  * No
  
==== General issue ====

 * PRFPMI locked
  * 1.2 W output from IMC (7 W when O3GK)
  * Two hours with current best sensitivity
  * Noise hunting
   * MICH and PRCL feed forward implementation
    * MICH done, PRCL ongoing
   * Vibration of OMC leg
    * Investigation done, hunting ongoing
   * Vibration around IMC
    * Ongoing
   * Vibration around IFI chamber
    * The capper structure may inject the vibration, we will remove it next week 
    * To be air pressure in IFI area today
   * Noise budget evaluation
    * MICH, PRCL, CARM, Intensity, etc   
    * Suspension sensing noise
   * Interferometer characterization
    * Increasing the power at REFL table
    * Control filter optimization
   * Suspension control
    * Now evaluating the suspension control noise
     * IMC's -> much less than sensitivity curve
     * PR's done
     * SR's done
     * BS : ongoing
   * Increased the laser power
  
 * 出張PEM injection ([[https://gwdoc.icrr.u-tokyo.ac.jp/cgi-bin/private/DocDB/ShowDocument?docid=14016|planning form]])
  *
