Weekly PEM meeting
- 2023/04/28(Fri) 17:00-
- Regular meeting
Zoom2 : https://zoom.us/j/6676627462
General announcement
- If you or your student/stuff have interested in the new PEM activity, please contact to me
- New member
- O4a run will start from 24th May
- 4 weeks run it will finish 21st Junne
- Mostly onsite and Mitaka member will have a shift for observation
- Not disagree that offsite member come KAGRA during run
- CAL/DET week from 17th May
- We will stop the innterferometer update
- SEO budget to PEM is limiting
- KAGRA visiting plan
- Now, the budget of KAGRA is limiting, but if you want to visit Kamioka, please contact to Yokozawa

General issue
- PRFPMI locked
- 1.2 W output from IMC (7 W when O3GK)
Best more than 1.0 Mpc (Yokoyama-san announced)latest sensitivity
- Activities this week
- ASC using wave front sensors and ADS, BPC and so on
- Higher frequency WFS to reduce the fluctuation of IR transmittance power
- Tapping test day
- Tapping both end (Explained later)
- CAL day
- Analysis is ongoing, we may believe the BNS range
- Overnight silent run
- We can start the keep the observation state
- Implementation of the good oplev record guardian
- Implementation of the high bandwidth WFS control
- Lock loss study
- We can start the keep the observation state
- ASC using wave front sensors and ADS, BPC and so on
- (Future) Interferometer characterization
- Increasing the laser power
- Continuous tapping test
- Center area at Saturday
- Alignment sensing and controls
- Control filter optimization
- Suspension control
- Now evaluating the suspension control noise
- Increased the laser power
- Silent run
- Currently, if the lock state is observation, this would be silent run
- 1.2 W output from IMC (7 W when O3GK)
出張PEM injection (planning form)
Jurnal paper issue
- Micro seismic analysis (Hoshino)
- writing
- Acoustic reverberation time paper (Washimi+)
- Suspend
- Re-measurement before O4?
- Tonga GIF paper
- Referee comments
Preparation for O4
- Environment will be fixed today
- Turned off the cooler and heater at the same time
- High resolution heater
- Finalize the PEM installation
- Accelerometer to C chamber and TMS table (Maybe postpone after O4a, lower priority)
- Microphone to C chamber (Maybe postpone after O4a, lower priority)
- Investigation of the PEM injection
- Tapping test is higher priority
- Acoustic injection preparation
- Output sound smaller compared from O3GK's
- Magnetic injection
- After O4a?
- Voltmeter preparation
- We made the PEM channel
- K1:PEM-VOLT_{PSL,IMCREFL,REFL,ISS,AS}_TABLE_{GND,FLOAT,DIFF}
- K1:PEM-VOLT_OMC_CHAMBER_{GND,FLOAT,DIFF}
- AC power monitoring
- Bought transreducer
- Prepared
- DC power monitoring
- Arrived at Kamioka
