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: 17th October).

    • See the detail in url

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

• PTEP paper
  • [kagra 03133]
  • KAGRA Overview papers
  • Overview of KAGRA : (3) Detchar, calibration, physical environment, data quality
• Next F2F meeting
  • RESCEU
  • 4th and 5th Dec., 2019

  • 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

    • ALS, the green fiber noise
    • LAS, ISS noise hunting
    • MIF, FPMI displacement

    • Wide 44Hz noise -> Vacuum pump?

    • BS
• 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 : New vacuum pump, 18V DC noise(24Hz), Cryochamber vibration(46Hz)
  • Database for the KAGRA characteristic lines
