* PRFPMI with OMC DC readout
  * 1.2 W output from IMC (7 W when O3GK)

  * Noise hunting
   * (ongoing) MICH/PRCL feed forward tuning 
   * (ongoing) Turning off the instruments (Especially vacuum pumps(TMP))
   * Investigating the noise from the vibration
    * OMC leg
    * IMC
    * IFI
    * etc
   * We opened the IFI chamber and remove the material which was connected between IFI chamber and IFI optical table in vac
    * Motivation was to extract the thermal from PRM reflection beam
    * After this work, the sensitivity is improved
    * Latest sensitivity [[https://dac.icrr.u-tokyo.ac.jp/KAGRA/DAWG/Detchar/klog/klog24301|wiki]]

  * Silent run
   * Latest one [[ https://klog.icrr.u-tokyo.ac.jp/osl/?r=24301|klog24301]]

  * Future work
   * Evaluate the noise budget 
    * Turned off the instruments
    * Check the scattering light
    * Hammering test/Acustic injection
   * Suspension control optimization
   * Alignment sensing and control
    * ADS and ASC
   * Interferometer characterization
   * Increased the laser power
