Weekly PEM meeting
- 2023/04/14(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
- 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

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
- BPC at center area
- Problem of the discrepancy between green and IR
- Problem of how to align to the OMC after ASC performing
- MICH and PRCL feed forward implementation
- To find the time
- 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

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
