  * Vacuum: *木村、上田、宍戸、高橋
   * 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戻したような状態。しばらくは現状のまますすめて。来週もう一度トライする予定。		   * Vibration Isolation,
   * Restarted the BS realtime model.
Line 64: Line 62:
  * 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にも光は返ってきた。
    * 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: Izumi, Okutomi
   * ETMY transfer function has a different shape from what was measured before in the air. It means that ETMY might be touching somewhere.
    * For vertical, below BF transfer function seems to be OK.
    * Yaw might be rotating too much.
     * After 1/17, ETMY started showing something strange. Stiffness changed gradually, but Q did not change much.
Line 76: Line 70:
  * Vacuum: *和泉、早河
   * 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 79: Line 71:
  * IOO: *苔山
   * 今日一日光を使う。		   * Alignment: *Izumi, Okutomi
    * We will rotate IP yaw to release somewhere touching. This work takes 1day at least.
    * Detchar for spectrum of suspension is necessary as soon as possible.
Line 82: Line 75:
  * Alignment: *和泉
   * 午後にOplevの再センタリングをしたい。WABと時間調整。		   * Vacuum
    * Gate valve will be closed today.
    * Needs 2days for evacuation. If once evacuated, cooling will be late ~2weeks.
 
  * Type B
   * SR assembly continues.
Line 85: Line 82:
  * 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。アラインメントと時間調整。

  * 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. At some in this evening, it will be the are over the SR line for double-checking the IMC alignment. Kokeyama is responsible for it.
Line 95: Line 85:

  * Week of 1/29
   * 1/31-2/2 Re-checking main beam to ETMY
Line 100: Line 86:
   * 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 104: Line 91:
  * Network cableの整理
  * EYVのピストン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。		   * The ETMY mirror showed a strange scattering pattern.
