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)
- Before bKAGRA phase1 run (Detailed date has not been fixed): Preparation
- Beginning of Feb. (2018): 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

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
Number of usable channel for each rack
★ 最低限なにかしらのDAQがほしい場所
- MC、PRエリア(IMC0ラックに寄生?)
- BS、SRエリア(PR2ラックに寄生?+追加のADCはここ)
- IXCエリア(WABラックに寄生?)
- IYCエリア(WABラックに寄生?)
- EXCエリア(???誰)
- EYCエリア(???誰)
- IXVエリア(TypeAラック、CryoP?)
- IYVエリア(TypeAラック、CryoP?)
- EXVエリア(TypeAラック、CryoP?)
- EYVエリア(TypeAラック、CryoP?)
- 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。
(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。)
Make analysis codes --> Hayama, Pil-jong
- Gather all required instruments listed in above tables.
持っている機器、買う必要がある機器の確認し、見積りを取る。-->長野
- 小さい加振機の検討。
例えば、https://www.monotaro.com/g/02599650/とか、https://www.toyo.co.jp/mecha/products/detail/themodalshop-2002e.html#link3とか。
- 必要ならRobertに聞いてみる。
- アナログ回路(~10 kHzの早いインジェクション用)を作る。
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。
- 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。
- 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
磁束計のセットアップ --> 田中
ラックの状況をまとめる --> 三代
ホワイトニングフィルターの確保 --> 端山
加振機の確保 --> 三代・端山
コイルの作製 --> 長野
磁束計の検討 --> 長野
既存のセンサー・アクチュエータのリスト化 --> 端山(シフトコール)
- MEDM画面の作成
- 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。

Meetings
Next meeting is ???????????????
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。
