Minute of PEM meeting
- Date: 2019/7/2 17:00-18:00(JST)
- Attendance: Yokozawa, Washimi, TTanaka, Okawa, Fujikawa, Mori, Kozakai, Kaihotsu, Miyo, Oshino, Yamat
=== 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???)
- Task list toward the O3
- Please send e-mail to me if you have comments.
- KAGRA interferometer status
- each member progress
- Yokozawa
- Power supply issue
- We started the investigation around the EX0 rack today.
- With Pcal noise investigation
- Power supply issue
- Washimi
- Others and plan toward the JPS meeting
- Google chrome project
- Accelerometer and microphone
- They are very useful, especially potable feature is great.
- Several spectral with short spectrogram was shown
- Others and plan toward the JPS meeting
- Kozakai
- Trigger event identification
- Debugging now
- Current a few days failed?
- Yuzu summary page comments
- Others and plan toward the JPS meeting
- Trigger event identification
- Miyo
- Effect the protect shied to the seismometer
Long term study of the KAGRA ground motion Link
- One year trend is now opened consistent with Sekiguchi-san. Time variance check.
- 0.2Hz source dependence (0.15Hz??)
- 1.2Hz came from the ikenoyama river, observed during bKAGRA phase1
- Future issue is written in his github, welcome the comments
- Future discussion towards the English meeting
- Oshino
- Weather station issue
- Web page ready, pick up information by the k1script ready, remaining issue is making the epics channel and caput
- Weather station issue
- TTanaka
- Preparing for the PEM injection
- Speaker will be arrived tomorrow
- Microphone calibration
- Check with the coherent and non-coherent component
- Thesis agenda and plan toward the JPS meeting
