* 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。 * 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 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: *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。 |

* 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 * 午後にOplevの再センタリングをしたい。WABと時間調整。 |
* Type A: *Yokozawa * RT model of Type A will be separated into cryopayload and tower. * Type B * SR assembly continues. |

* 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. Green might be used late of the afternoon, then the center area and Y end will be the hazard area. |
