Weekly PEM meeting

  • 2019/12/10(Tue) 16:00-(JST)
  • Regular meeting meeting (Japanese)
  • Web meeting with Zoom2 (Zoom2)

Agenda

  • General issue
    • Interferometer status
      • Detection range is about 10kpc (or 30kpc(?))
      • There is still some peaks in the lower frequency
      • Mostly AS PD noise at higher frequency
      • Peaks appeared at higher frequency
      • December 17-24 24h engineering run
  • Conference
    • JPS (2010/3/16-19 @ Nagoya)
      • Yokozawa, TTanaka
  • PEM injection
    • Shaker injection1 (TTanaka, Yokozawa)
      • Where is the PZT shaker driver?
      • Acoustic injection -> Shaker injection

    • acoustic injection (TTanaka, Yokozawa)
      • PSL, REFL and AS table injection
      • Analysis is ongoing
    • magnetic field injection (Niigata Tanaka, Fujikawa, Yokozawa)
      • Effect of the air cooler magnetic field
      • AS, REFL table injection
  • Newtonian noise measurement
    • Thank you for Virgo PEM member!
    • Francesca mainly measured the newtonian noise
  • PEM measurement
    • Sunday morning : PEM injection
    • 10th Dec. : Xend environmental check
    • Someday : Effect of the sound to DARM displacement

    • Adam, Sheila (-12/13)
    • Camilla (-12/20)
  • Each progress
    • Yokozawa
      • Short report about newtonian noise measurement(Virgo PEM effort)
