PEM injection in bKAGRA phase1
(Description will be translated to English at some point)
Aims
bKAGRA phase1 における、
- 干渉計感度への環境雑音の影響のプロジェクション
- 散乱光のキャラクタリゼーション
- 雑音の形態学的スタディ
Injection types
- Acoustic injection (AcI)
- Magnetic injection (MaI)
- Shaking injection (ShI)
What we want to do
Necessary
- Measuring coupling functions between environmental noise and interferometer signal
- Measuring environmental noise using several sensors
- Spectrogram of the interferometer signal during injection
If possible
- Narrow down coupling locations
- Narrow down environmental noise source locations
- Switch off test
- Identify line noise sources
Candidates of measurement points
- PSL
- IMC (mirrors, refl table)
- IFI
- PRM
- BS
- ETMX/Y (1F,2F)
- WAB
- Arms
(including racks of each points for control and DAQ.)
Schedule
(VERY ROUGH)
- Before bKAGRA phase1 run (Detailed date has not been fixed): Preparation
- After bKAGRA phase1 run (Detailed date has not been fixed): Injection test in tunnel
- After injection test: Analysis, make report, (if possible) write paper
