Weekly PEM meeting

• 2019/9/3(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

  • Weekly PEM injection
    • Commissioning team suggest to have a weekly PME injection/measurement day with interferometer signal
    • First candidate : Every Friday
    • Show the plan for the PEM injection
  • Chrome Book project (Portable PEM researcher)

    • http://gwwiki.icrr.u-tokyo.ac.jp/JGWwiki/KAGRA/Subgroups/PEM/Portable

    • We prepared two PEM Chromebook
    • 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 16Hz noise investigation
      • BS , Serious 90Hz noise investigation
  • Task list toward the O3

    • task sheet

    • Please send e-mail to me if you have comments.
