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

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？）

    • 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。

(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 to connect all instruments.
    • Ground problem. (各実験エリア(特にエンド)でのグラウンドの確認。)

  • 各エリアで確保できるデジタルのチャンネル数の確認。--> EXC: 端山、EXV: 端山、IMC0: 三代、BS: OK

  • 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。
  • 予行演習・本番測定の人手の確保。
  • 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

Meetings

Next meeting is 2018/1/16 13:00-- Detchar meeting

What has been done

  • Consider how many DAC, ADC, CH are required at each measurement point.
  • 大きい加振機の所在を麻生さんに確認。
  • Differential input/output of CDS. (CDSの差動入出力への対応。)
  • Consider how many people are required.
  • 解析コードを作る人手を確保。

  • 磁束計の検討 --> 長野

  • ホワイトニングフィルターの確保 --> 端山

  • 山本さんにCALで似たようなコードを作ってないか確認する。

Paper plan

  • 腕方向の地面振動のキャビティ的蓄積
