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
