• Date: 2019/9/3 17:00-18:00(JST)
• Attend：Yokozawa, TTanaka, Ohkawa, Fujikawa, Oshino, Kaihotsu, Washimi, Mori
• Agenda
  • Yokozawa
    • Coherent analysis for the FPMI, MICH and SRCL

      • klog10109, klog10182, klog10235, klog

    • List of the PSL vibration noise frequency

      • klog10173, list

    • Prepare for the TAUP2019
      • Need to discuss about the topic.
  • Washimi　
    • Magnetic field simulation and lighting issue
      • Magnetic field from the lightning generates higher frequency ~5kHz, so SF changed to 16kHz
      • Make summary page for magnetometer
      • 9/12 lightning expert will visit Kamioka and discuss.
    • Other portable PEM collaboration

    • Conda usage -> ASC analysis

    • Discussion about the fujimopy
    • Online Jupyter with GWpy
    • Update the channel names for portable PEMs
  • Kozakai
    • Glitch issue
    • Night shift summary
    • Pick up the requirement to PEM for the JPS meeting
  • TTanaka
    • Preparing for the PEM injection
    • Make shell file and check with control PC tomorrow
    • impact hummer
  • Miyo
    • Seismic motion issue if there is topic
  • Okutomi
    • Shaker injection

    • Comparison between portable PEM and KAGRA ADC PEM

    • Vacuum pump turned on and offpdf

      • Investigation about the 312.5, 315,450 and 460Hz
      • If we turned off the PR2 vacuum pump, 312.5Hz was reduced.
  • Fujikawa, Mori
    • Fujimopy
      • GUI interface
      • Analysis from the frame files

      • sound files -> need lalframe library

  • Fujikawa
    • Lockloss with earthquake
      • check the guardian state and important channels and PEMs
      • magnitude is strongly dependent with lock loss?
