• 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

Edit conflict - other version:

• SR3, serious 16Hz noise investigation
