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 wiki
- Silent run
  - Latest one 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
