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)
  • 2018/04/09-13: Second rehearsal
  • After bKAGRA phase1 run (Detailed date has not been fixed): Injection test in tunnel (2 days)
  • After injection test: Analysis, make report, (if possible) write paper

To be prepared

  • CDS (Real time model, DAC, ADC, DQ)
  • Calibration (Sensors, DAC, ADC)
    • ADCの入力インピーダンスは10 kΩ (ref. JGW-T1200779 or Shoda-san's PhD thesis.)

  • Analysis code to calculate coupling function (peaks, comb, broad)
  • Spectrogram tools
  • MEDM

Calibration

  • ADC: (for single-ended sensors) 20/215 V/count (0.0006103515625), (for differential sensors) 10/215 V/count (0.0003051757812)

    • input impedance 10 kΩ
  • Small magnetometer (Mag649, Range +/-100 uT): 30 mV/uT (from manual)
  • Microphone (BRÜEL & KJÆR 4188): 31.6 mV/Pa (from manual)

  • Microphone2 (AUDIO-TECHNICA AT-VD6): ~320 mV/Pa (with Max gain, from measurement)
  • photosensor for toy pendulum (リハーサルのインジェクション対象): 1.12 V/mm (@4.2mm(micrometer), from measurement)

Number of usable channel for each rack

★ 最低限なにかしらのDAQがほしい場所

  1. MC、PRエリア(IMC0ラックに寄生?)
  2. BS、SRエリア(PR2ラックに寄生?+追加のADCはここ)
  3. IXCエリア(WABラックに寄生?)
  4. IYCエリア(WABラックに寄生?)
  5. EXCエリア(???誰)
  6. EYCエリア(???誰)
  7. IXVエリア(TypeAラック、CryoP?)
  8. IYVエリア(TypeAラック、CryoP?)
  9. EXVエリア(TypeAラック、CryoP?)
  10. EYVエリア(TypeAラック、CryoP?)
  11. Xアーム (PX1ラックに寄生?)
    • BNCの配線を考えると、コレぐらいのエリアが最低限で現実的。
    • 最初はざっくり10枚ADCがほしいとリクエストしてみましたが、無理でした。

To do list

Currently, to do list is managed in github project (github issue): https://github.com/gw-analysis/detector-characterization

Current milestone: (On-site) Install sensors and consider their operation, (Off-site) Analyze rehearsal data and prepare actuators (by 2018/03/30)

  • Obtain S/N on JGWdoc for all PEM related things, e.g. sensors, actuators, amplifiers, non-standard cables.
  • アナログ回路(~10 kHzの早いインジェクション用)を作る。
  • 確保できるチャンネル数の中で、やること/できることを具体化する。
  • センサー・アクチュエータ類のキャリブレーション。
    • 主にコイル(他はマニュアルを信じる) --> 長野

  • 磁束計Mag13のセットアップ --> 田中

  • MEDM画面の作成 --> 誰か+シフト

    • フィルターバンクに各センサーのキャリブレーションファクターを入れておく。
    • イメージはこんな感じ。MEDMdesign_PEMinjectionVer2.png

  • エンドでの作業手順(2階へのものの搬入、クリーンブース内の中2階へのアクセス方法等)をTypeAチームに相談する。
    • Xエンド2階へはT3で、Yエンド2階へはキャタピラ付きのキャリー(名称不明)で坂を登って運び入れている(by奥富さん)。
