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
