  * Vacuum: 木村
   * Gage valveが空いた。真空度はざっくりArm:1e-6 Cryo:1e-4で、徐々に平衡状態になっている。
   * EYVの6本のピストンのうちの3本をリリースして防振系をフリーにしようとしたが、結局フリーにはならず、2mm下がって、0.5mm戻した。しばらくは現状のまま行く。来週もう一度トライ。。

  * Alignment: 和泉、桐井、道村、奥富
   * Glitchの原因がどうやらLVDT関連の電気系である可能性が高まった。すくなくともメカ系ではなさそう。
   * LVDTのDACにオフセットを加えると現れる。
   * エンドでのビームはシャッターを開けたらすぐにETMYには届いたが、ゲートバルブが空いていなかったようで、バッフルPDに光が届かなかった。BSには光は返ってきた。
   * BSに光を返すとOplevで見てYawに線形領域を超えるくらいずれていた。

  * 機器制御のチェック: *麻生、日立造船
   * センター、各エンド64chが使えるようになった。
   * Alignment and Vibration Isolation: Izumi, Okutomi
   * BF yaw transfer function showed that it did not move well. It was fount that the position of IP was different from when pumping down started.
   * IP drifted 2mm in the air, and another 2mm when pump down. (Takahashi)
   * ETMY IPs were set back to where they were on 1/13. The transfer function now has the similar shape as before, but the Q of lowest peak is a bit low.

  * Vacuum: *木村、上田、宍戸、高橋
   * ゲートバルブにまずgate valveを開け、その後今日の午前にEYVの6本の足のうちの3本をリリースして防振系をフリーにする。
Line 77: Line 66:
  * IOO: *苔山
   * 今日一日光を使う。		   * Alignment and Vibration Isolation: *Izumi
   * We can move moving masses of BF, or IPs of yaw to check TF can be recovered.
   * We will play one more day under vacuum.

  * Alignment: *和泉
   * 今日の夕方、全員が出坑してからバッフルPDのチェック。
   * 午後にOplevの再センタリングをしたい。		   * Type A: *Yokozawa
   * RT model of Type A will be separated into cryopayload and tower.
 
  * Type B
   * SR assembly continues.
Line 84: Line 76:
  * WAB: *阿久津
   * 作業と重なるのでビームをできるだけ避けてほしい。

  * Type B
   * Blade inspection.
   * Re-centering oplev.

 * Laser hazard: 現在PSL。今日は午後のある時点でアラインメントのためSR2-3ラインより奥に変更。アラインメント完了後、PSLに戻す。		  * Laser hazard: PSL. Green might be used late of the afternoon, then the center area and Y end will be the hazard area.
Line 94: Line 79:

  * Week of 1/29
   * 1/31-2/2 Re-checking main beam to ETMY
Line 99: Line 80:
   * 2/5 Cooling start.    * Finding causes of ETMY trouble.
    * Evacuation might be needed if ETMY is touching somewhere.
    * Cooling also will be delayed for 2weeks or so.
Line 103: Line 86:
  * Network cableの整理
  * EYVの足のリリースで防振系がフリーにはならない。
  * Leakが二箇所残っている。		   * IP drifted 2mm in the air, and another 2mm when pump down.
