  * Alignment: *Izumi
   * EYのBaffle PDの回路を接続して準備が完了した。18時頃からBSからETMY方向にビームを飛ばしリサージュで振り始めた。
   * ビームはまだ確認できていない。ゲインが500倍くらい低かったせい。再度ゲインを上げて試す。
   * CryopayloadでもYawが動かないことがあったので、当たっている可能性があることがわかった。 		  * Vibration Isolation,
   * Restarted the BS realtime model.

  * 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.

  * Alignment: *Izumi
   * 午後3時か4時頃から、再度ゲインを上げてETMYでの確認を試す。
   * CryopayloadのVisual inspection.
   * φ800フランジは今日は開けておく。明日閉める。
Line 76: Line 71:
  * IOO: *Kokeyama
   * 1WをMCに入れる。		   * 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 79: Line 75:
  * 真空引き判断
   * チェックリスト最終確認。
   * 最速で今日の夕方ETMYで光が見えて、うまくいけばBSでもすぐに見える。
   * おそらくビームがBSまで返って届いているかの判断は明日朝になりそう。ただしリモートで全てできることなので、ビーム確認なしで真空引きをする可能性もある。
   * Cryostatのタッチがないかを確認。
   * φ800フランジを閉める。		   * 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 86: Line 82:
   * Laser hazard: Upstream of IMM line in the daily time. All area after evening for the alignment.  * 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.
