Weekly PEM meeting

Agenda

Conference issue

  • JPS meeting
    • Online meeting web

    • 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?)

General issue

  • Interferometer status
    • Now interferometer is "suspend mode"
      • Measurements without interferometer
      • Keep the IMC lock
      • Check the green laser flash
    • Earthquakes at Hida area is serious
      • Large frequency
      • Close from KAGRA. Damage to alignment
  • Tasks for post-commissioning
    • post commissioning

      • Vibration measurement for OpLevs (+Ushiba, 6/1,3,4)

      • Acoustic injection (nest nest week?)
        • Day 1 : For only REFL (remote work) -> study of nonlinearity & up/down conversion (washimi will make more detaid plan)

        • Day 2 : For each booth (mine work) -> noise budget

      • Scattered light
        • One of the hammering test
        • OMC chamber vibration RMS
      • Line noise investigation by PEM
  • PEM meeting schedule
    • Washimi needs to join the VIS meeting (Fri. 14:00-15:30)
  • Working style (COVID-19 related)

Jurnal paper issue

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