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
RF noise measurement around RF modulation sideband frequencies.
- RF modulation sideband frequency list

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 and rehearsal of PEM injection (end-to-end test, maybe without actual injection)
After bKAGRA phase1 run (Detailed date has not been fixed): Injection test in tunnel
After injection test: Analysis, make report, (if possible) write paper

(Part of) to do list

Obtain S/N on JGWdoc for all PEM related things, e.g. sensors, actuators, amplifiers, non-standard cables.
Calibrate sensors and actuators.
- Consider how to calibrate them.
Consider how many DAC, ADC, CH are required at each measurement point.
Consider how many people are required.
Make analysis codes
Gather all required instruments listed in above tables.
