PEM injection in bKAGRA phase1

(Description will be translated to English at some point)

Aims

In bKAGRA phase1,

  • Investigate the projection of the environmental noise effect to the sensitivity of KAGRA interferometer
  • Characterize the effect of the scattering light
  • Morphologically study the environmental noise waveform

(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.

Candidates of measurement points

  • PSL
  • IMC (mirrors, refl table)
  • IFI
  • PRM
  • BS
  • ETMX/Y (1F,2F)
  • TMS (both end)
  • WAB
  • Arms

(including racks of each points for control and DAQ.)

Schedule

(VERY ROUGH)

  • 2017/12/06 Project started
  • 2017/12/26 Rehearsal of rehearsal
  • Before bKAGRA phase1 run (Detailed date has not been fixed): Preparation
  • 2018/01/11-12: Preparation of reharsal
  • 2018/02/13-15 (option 2/16): 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 (4 days)
  • After injection test: Analysis, make report, (if possible) write paper
