- 312.5Hz search
- Coherent analysis with PEMs
- Washimi
Cryochamber characterization
Sound reverberation analysis
Kaminari monitoring
Google chrome : USB magnetmeter 2 USB_MAG_2.jpg
- イヤホンジャックを使わなくてもよくした。
Seismometer vs accelerometer analysis : silde
- TEAC710はLで100倍、TEAC706は、10倍ということがわかった。
- Kozakai
- Trigger event identification
- Reprocess the 2nd engineering run
- Glitch signal can be seen by hardware injection(SG)
- PEM injection, maybe not glitch because the long signal
- For checking, hardware injection is better than PEM injection
- 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 (If there is update)
- Ground motion at last Friday(7/19) (I want to ask you to have a report of large ground motion)
- TTanaka
- Preparing for the PEM injection
- Report of the PEM injection during 2nd engineering run
- Lineに合わせて、injection
- cable noiseに気をつける
- chromebookからインジェクション
