Weekly PEM meeting
- 2020/05/08(Fri)
- Just for memo
Agenda
General issue
- Interferometer status
- Two weeks observation was completed
- Earthquakes at Kamikochi(上高地) is serious
- Large frequency
- Close from KAGRA. Damage to alignment
- Now interferometer is "suspend mode"
- No measurements
- Keep the IMC lock
- Check the green laser flash
- Tasks for post-commissioning
- Scattered light (One of the hammering test)
- OMC chamber vibration RMS
- PEM injection
- Line noise investigation by PEM
- PEM papers (Writer)
KAGRA summary paper(Yokozawa)pdf
- Part of the KAGRA overview paper
- PTEP (Overview of KAGRA : (3) Detector characterization, calibration, physical environment, and data quality)
- Installation
- Technical issue
- Acoustic injection paper (Washimi)
- Target journal
- Request 3+8 hours data taking to commissioning
- Portable PEMs (Yokozawa)
Target journal->to be discussed later
- Chromebook+USB PEMs, aco power supply+BNC PEMs+KAGRA DAQ
- Ground motion paper (Yokozawa)
