  * 現在ビームをYエンドだけでなく、Xエンドでも見失っているので、今日真空槽内を見てチェック。Oplevではセンターの鏡はセンターを示している。
   * 真空槽を閉めても外からビームをトレースできるカメラなどの手段が必要なのでは。(宮川)
  * ダンピングループはYawのピークを何本か落とせた。
  * Heat linkの影響の計算をした。(宮本、牛場)
   * Type Aの20mHzの共振周波数がHeat linkであがる可能性の説明はつく。		   * Beam was found again at the ETMX and ETMY by alignment to IYA viewport using PR3.
   * We need absolutely beam monitor like camera, PD etc, even if all the chambers are closed.
  * Effect of Heat link to hardness of Yaw motion(Miyamoto, Ushiba)

Minute of KAGRA commissioning meeting

  • Date: 2018/3/6 11AM~12PM
  • Attendance: Miyakawa, Uchiyama, Miyoki, Aso, Akutsu
    • eZuce: Izumi, Enomoto, Kimura, Suzuki, Tomaru, Ushiba, Inoue, Hirose

1. Report of work of the last week and plan of work

  • Alignment, ETMY: Enomoto, Izumi
    • Beam was found again at the ETMX and ETMY by alignment to IYA viewport using PR3.
      • We need absolutely beam monitor like camera, PD etc, even if all the chambers are closed.
    • Effect of Heat link to hardness of Yaw motion(Miyamoto, Ushiba)
    • Height of the PR2 and PR3 did not change much. Beam was misaligned mainly at the MC. QPD for MC transmitted monitor was recovered and the beam was aligned according to the MC monitor.
  • Alignment to REFL port
    • Scheduled after duct connection.
  • Cryo:
    • Current temperature is ~40K. Speed of lowering temperature increased in these 3 days.

2. Schedule of ETMX installtion

  • See schedule

3. Tasks or discussions

Feed back to BS for MICH

  • Experimental side:
  • Data analysis side:
  • LSC model(Michimura, Izumi)
    • Same as iKAGRA or full model?
    • CAL model location? which PC?

  • Selection of storing DAQ channel -> DGS, before phase 1

    • Check the total amount.

  • Screens at control room -> who, when?

    • Needs laser safety information.

  • GW alert: online alert in the control room might be prepared. -> Togoshi

4. Phase2

Others

  • Next meeting: 3/13
