  * 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。		   * Yend baffle PD did not work, but power supply was off.
  * Beam was found again at the ETMX and ETMY by alignment to IYA viewport using PR3. Beam will be returned to center this week.
   * Beam at the REFL port will be checked this week, but beam will be limited by vacuum work, so time sharing is needed.
  * We need absolutely beam monitor like camera, PD etc, even if all the chambers are closed.

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
    • Yend baffle PD did not work, but power supply was off.
    • Beam was found again at the ETMX and ETMY by alignment to IYA viewport using PR3. Beam will be returned to center this week.
      • Beam at the REFL port will be checked this week, but beam will be limited by vacuum work, so time sharing is needed.
    • We need absolutely beam monitor like camera, PD etc, even if all the chambers are closed.
  • CAL:
    • X end PD will be removed. Baffle PD will be located instead. Changing PD will be done around 3/26.
  • PRs:
    • 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.
    • LVDT had several jumps due to the power outage. The calibration also may change.
  • Effect of Heat link to hardness of Yaw motion(Miyamoto, Ushiba)
  • Cryo:
    • Current temperature is ~40K. Speed of lowering temperature increased in these 3 days.

2. Schedule of ETMX installtion

  • See schedule
    • Check list for ETMX, Center.
    • Improved point for EMTX should be shared to Vacuum team. It will be listed and shared.
      • Bug list is made by izumi-kun, it will be merged to above list.

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
