Line 59: Line 59:
  * 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 and Vibration Isolation: Izumi, Okutomi
   * Searching optimal position of IP of ETMY resulted that the stiffness (DC response level) is the same as what it was measured in the air. Still something at lower stage might be hitting somewhere.
  * Mirror view by Tcam also moved by 6mm order! It means that the calibration of LVDT can be wrong by factor of 25.
  * The result of fine tuning showed 1mm off to -x direction.
Line 63: Line 64:
  * 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。
 * Vacuum: Kimura
  * Another leakage was found with 1e-8 order (2 order of magnitude larger than other two). We leave it anyway and we will start cooling.
Line 74: Line 68:
  * 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 69:
  * IOO: *苔山
   * 今日一日光を使う。
  * Cooling: Kimura, Suzuki, Yokozawa
   * We will start cooling around 11AM.
Line 80: Line 72:
  * 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。
  * Alignment: Izumi, Miyakawa
   * Oplev of ETMY will be monitored at the control room, and misalignment will be restored remotely during the cooling.
Line 84: Line 75:
  * 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。
  * WAB cooling test: Akutsu
   * Temperature monitors are being prepared.
   * Oplev is ready.
Line 87: Line 79:
  * 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 will be used all the day, then the center up to PR3 will be the hazard area.
Line 94: Line 82:

  * Week of 1/29
   * 1/31-2/2 Re-checking main beam to ETMY
Line 99: Line 83:
   * 2/5 Cooling start.   * 2/7 Cooling.
Line 103: Line 87:
  * 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.
