=== Agenda ===
- General issue
- KAGRA interferometer status
- PRC loss was large, birefringence effect?
- FPMI or SRFPMI or DRFPMI
- Open the CS area and remove the PRM and SRM?
- Before that, we want to investigate the scattering effect at CS area
- Chrome Book project
- Portable PEM researcher
- Spectral analyzer, sound recording, ...
USB accelerometer (Center area), microphone, ...
Data sharing GoogleDrive
- Weekly PEM measurement
- Friday is temporal weekly PEM measurement
- Understanding the effect of the instruments and so on
- Power supply
- duct vibration
- PEM DAQ sampling rate
- Due to the limited DAQ power, almost all PEMs are taken at 2kHz sampling
- Only PSL and CS microphone are taken with 16kHz sampling for the noise hunting
- PEM injection
- Shaker injection1 (Yikang, Yokozawa)
- Shaker injection2 (Okutomi, Fabian)
- acoustic injection (TTanaka)
- magnetic field injection (Yikang, Yokozawa)
- RF injection (TTanaka, Washimi)
- 1st engineering run
- 1st engineering run : Jun. 8th 12:00-18:00(JST) : Xarm cavity
- Preparing toward the next engineering run
- Next engineering run : 13th Jul.
- Interferometer configuration ?
- English meeting
- We will have a monthly English meeting(Mainly share the information with Virgo people)
- The third Tuesday of every month 17:00-(JST) 10:00-(CEST)
2nd meeting will be held at 16th Jul.(Tue) 17:00-18:00 URL
- Seismon issue
- We already installed to KAGRA system
- Need the tuning for the KAGRA
- Large earthquake happened this month, we "should" be a safe mode before coming large earthquake (PEM issue???)
