Weekly PEM meeting

  • 2019/10/29(Tue) 16:00-(JST)
  • Regular meeting meeting
  • Web meeting with Zoom2 (Zoom2)

Agenda

  • General issue
    • Interferometer status
      • We tried to lock the FPMI now, there is a problem in the hand-off from the green to IR main laser
      • Several morning runs were held (Ex: 8th October).
        • See the detail in url

        • Silent run -> Some excitation(including calibration line) -> PEM injection -> Hardware injection

        • Current IFO urgent noise
  • PTEP paper
  • Next F2F meeting
    • Chrome Book project (Portable PEM researcher)
      • http://gwwiki.icrr.u-tokyo.ac.jp/JGWwiki/KAGRA/Subgroups/PEM/Portable

      • We prepared two PEM Chromebook
      • Start writing paper (PTEP?)
      • There are many project to collaborate with the instruments
        • IOO, vibration, sound and magnetometer measurements inside the PSL room klog10173, list

        • ALS, the green fiber noise
        • LAS, ISS noise hunting
        • MIF, FPMI displacement
        • VIS, Around the OpLev

        • Wide 44Hz noise -> Vacuum pump?

        • BS , Serious 90Hz noise investigation
    • PEM injection
      • Shaker injection1 (TTanaka, Yokozawa)
      • Shaker injection2 (Okutomi, Fabian)
      • acoustic injection (TTanaka, Yokozawa)
      • magnetic field injection (Niigata Tanaka, Fujikawa, Yokozawa)
      • RF injection (TTanaka, Washimi)
    • Weekly PEM measurement
      • Friday is weekly PEM measurement
      • Understanding the effect of the instruments, search the origin of noise, and so on
      • Tentative : coherent PEM channels with FPMI displacement(Last Friday), New vacuum pump(This week)
    • Database for the KAGRA characteristic lines
    • Visitors from LV
      • Anamaria from Livingston : after commissioning break (she will decide the visiting plan at end of October)
      • Federico, Irene, Camilla (input optics) + 1? from Virgo : 11/18-12/7 (2 weeks@KAGRA, 1 weeks@NAOJ)
