- To Kamioka
- Fukunaga (2/20-2/24)
- 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
- Now evaluating the suspension control noise
- Increased the laser power
- MICH and PRCL feed forward implementation
出張PEM injection (planning form)
Jurnal paper issue
- ICA for E-run/O3GK (Kume, Kobayashi)
- Received the accept from CQG
- Micro seismic analysis (Hoshino)
- writing
- Acoustic reverberation time paper (Washimi+)
- Suspend
- Re-measurement before O4?
- Tonga GIF paper
- Playground application
Preparation for O4
- Many portable accelerometer to chamber and beam ducts
- Checking the vibration effect from vacuum pumps
- Evaluating the effect to OMC leg
- Remove after hammering test
- Finalize the PEM installation
- Accelerometer to C chamber and TMS table
- Microphone to C chamber
- Do we need both booth and field?
- Investigation of the PEM injection is just started
- Acoustic injection preparation
- Output sound smaller compared from O3GK's
- Magnetic injection
- After O4a?
- Acoustic injection preparation
- Voltmeter preparation
