Weekly PEM meeting

  • 2020/05/29(Fri) 16:00-(JST)
  • Regular meeting meeting (Japanese)

  • Web meeting with Zoom2 (Zoom2)

  • member : Yokozawa, Washimi, Dan Chen, Kozakai, Ohkawa, Kume, Tomaru, Oshino, Fujikawa

Minutes

  • JPS meeting
    • Yokozawa will have a talk about PEM summary
    • deadline 6/4
  • 新学術地下宇宙 (6/2-4)

    • Online meeting web

    • Washimi has an invited talk on 6/3 slide (posted to the CPC)

    • Yokoyama-san also has a talk (not KAGRA?)
  • PEM meeting schedule
    • 16:00-17:00 Friday
  • Paper issues

    • KAGRA summary paper(Yokozawa) <<Almost DONE>>

    • Acoustic injection paper (Washimi) <<ON GOING>>

    • Portable PEMs (Yokozawa+)
      • Fix the contents and main result first
    • Ground motion paper (Yokozawa)

    • PEM summary note (Yokozawa+) <<ON GOING>>

    • Acoustic reverberation paper (Washimi+Virgo)
      • Start writing after the acoustic injection paper
    • Magnetic field paper (Washimi+)
      • section
        1. Introduction
        2. 1-year Geomagnetism in underground
        3. 1-year Schumann resonance in underground
        4. Mag. field in EXC chamber
        5. Coherence between PRFPMI and MAGs
        6. Lightning effect on PRFPMI (3/22 event)
        7. Conclusion
      • If rich contents, we should divide into several papers
      • Check the past schumann resonance paper
    • ICA analysis for E-run/O3GK (Kume, Yokoyama)
      • Start the code changing for the PEM injection data (before O3GK)
        • Is the time length (~100s) enough?
  • for O3c
    • Ondotori maintenance
      • Change to AC adapta
      • Ask ondotori maker about the special power supply for KAGRA

    • FFU operation & particle counter (if we open the OMC)

      • Ask Kokeyama-san about particle counter
  • for O4

    • cabling (github204)

      • IOO circuit part was completed, need to enter the mine
      • We have to make cable diagram before ask Gyousya
    • cosmic-ray/RI detector
      • ETが興味を持つ前にさっさと論文にするべき
      • 物品についてはSK, XMass, Kamlandに相談してみる。
      • fluxやdE/dxの観点から、宇宙線μよりもα線の方が影響が大きいか
        • 神岡鉱山はラドンの宝庫
        • 鏡の運動よりも、PDの空乏層の放射線損傷の方が効きそう
      • Investigate the effect of the radon to PDs and so on

        • 放射線耐性 -> 線源を買って加速試験

        • KAGRA坑内のflux -> プラスチックシンチレータなどで測定

        • 神田さんがプラシンで宇宙線の影響を調べている
    • Information from Tomaru-san
      • priorityはO4に置く O3cではなく。

      • OMCを開ける->リクエストを出す

      • 散乱光、IMC周りを開けた後ですぐに確認
      • ケーブルを抜いたりしたらノイズの振る舞いが変わる
