Weekly PEM meeting
- 2020/04/17(Fri) 14:00-(JST)
- Regular meeting (Japanese)
Web meeting with Zoom2 (Zoom2)
Agenda
General issue
- Interferometer status
- Two weeks observation was performed
- Very limited onsite people operated the interferometer
- End 4/20 9:00 a.m(JST)
- After that, calibration group may work
- Two weeks observation was performed
- Tasks for post-commissioning
- Scattered light (One of the hammering test)
- OMC chamber vibration RMS
- PEM injection
- Line noise investigation by PEM
- PEM papers
- Portable PEMs
- KAGRA summary paper (Preparation of PEMs is main target)
- O3 PEM paper
- Acoustic injection
- Noise budget (?)
- Task management 2020
- Join the PEM meeting
- Analysis related PEM (Need the communication with Yokozawa or Washimi)
- PEM installation toward O4
- Preparation for PEM injection
- If you will have efforts for PEM, please contact to Yokozawa or Washimi
- Preparation, development, update of new monitors will be added as PEM effort
- Example : update glitch plot, daily summary page.
But "just use them" may not include as PEM effort -> Shift or commissioning
Each progress
- Discuss about the general issue (Yokozawa)
- GND noise preparation after O3 post commissioning (Yokozawa)
Line noise subtruction (Washimi) : 60Hz power, 180Hz violin mode
- Glitch plot report (Kozakai)
- Yuzu summary page report (Yuzurihara)
- Update of the pastavi (Yuzurihara)
