From Kamioka
- No

General issue

PRFPMI locked
- 1.2 W output from IMC (7 W when O3GK)
- ~30 min with current best sensitivity
- Noise hunting
  - MICH and PRCL feed forward implementation
    - MICH done, PRCL ongoing
  - Vibration of OMC leg
    - Investigation done, hunting ongoing
  - Turn off instrument
    - TMP and related pumps off
    - FFUs, coolers, dry air
    - Temperature control difficult
    - Will stop more instruments
  - Vibration and sound around
    - Some peaks disappeared after stopped the TMP
    - Several peak remained with CARM related
    - Hammering test to optical table, chamber, beam duct and chamber leg, ...
  - Noise budget evaluation
    - MICH, PRCL, CARM, Intensity, etc
  - Interferometer characterization
    - Control filter optimization
  - Suspension control
    - Now evaluating the suspension control noise
      - IMC's -> much less than sensitivity curve
      - PR's ongoing
      - BS : suspect point
  - Increased the laser power
出張PEM injection (planning form)
