General announcement
- 2023年度、よろしくお願いします。
- If you or your student/stuff have interested in the new PEM activity, please contact to me
- Meeting schedule
- If there are no objections, I will keep the PEM meeting at Friday 17:00(JST)
- 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
- KAGRA visiting plan
- Now, the budget of KAGRA is limiting, but if you want to visit Kamioka, please contact to Yokozawa
- RRT shift

Business travel
- Depending on the situation of COVID-19
- To Kamioka
- No
- From Kamioka
- No
General issue
- PRFPMI locked
- 1.2 W output from IMC (7 W when O3GK)
- Best 1.0 Mpc (?)
- Activities this week
- ASC using wave front sensors and ADS, BPC and so on
- IMMT1 pitch would generate the XY asymmetry(transmittance power)
- Most problem would be solved
- Tapping test POP/PSL
- Report later
- MICH and PRCL feed forward implementation
- Next week
- ASC using wave front sensors and ADS, BPC and so on
- (Future) Interferometer characterization
- Increasing the power at REFL table
- MICH controls investigation
- POP table to REFL table
- Simulation
- Alignment sensing and controls
- Control filter optimization
- Suspension control
- Now evaluating the suspension control noise
- Increased the laser power
- 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
- Discussion of the portable PEM channels
- Still under investigation with the results of the tapping test
- 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 is just started
- 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
- We made the PEM channel
- After O4
- RF monitor with mokugo
- Tiltmeter
