Weekly PEM meeting

  • 2019/10/01(Tue) 17:00-(JST)
  • Regular meeting meeting
  • Web meeting with Zoom2 (Zoom2)

Agenda

  • General issue
    • Interferometer status
      • Several morning runs were held. They are silent run after the IFO commissioning.
        • We can use the PEM injection and calibration line study in future
        • See the detail in url

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

        • Current urgent noise
    • 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

        • SR3, serious 17Hz noise investigation

        • Wide 44Hz noise
        • 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
      • Power supply, duct vibration, instruments
      • Tentative : Magnetic field and its injection
    • Virgo visiting github

      • We will start the discussion to visit Virgo at October
