Weekly PEM meeting

  • 2019/10/15(Tue) 17:00-(JST)
  • Regular meeting meeting

  • Web meeting with Zoom2 (Zoom2)

Agenda

  • General issue
    • Interferometer status
      • 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
    • 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
