= Minute of PEM meeting =

 * Date: 2019/8/28 17:00-18:00(JST)
 * Attend：Yokozawa, TTanaka, Kaihotsu, Mori, kozakai, Washimi, Fujikawa, TTanaka(Niigata), Miyoki, Ohkawa, Kokeyama

 * Agenda

  * Yokozawa
   * Coherent analysis for the FPMI
    * Using Bruco, I evaluated the origin of the noise source during the FPmi 
    * Results are written in klog everyday

  * Washimi　
   * Magnetic field simulation
   * Lightning issue 
    * Discussion about the lightning monitor at 12th Sep.
    * monitoring the MAX/MIN magnetometer time series monitoring
    * There are lightning candidate around the evening
    * Full sampling rate time series monitoring
    * correlation between BS oplev was observed only 5th Aug.
    * PEM injection T~e-9 but 5thAug is e-6 level
    * Need very large coil
    * If we use the frame, we can make larger magnetic field
   * PSL 44Hz noise hunting 
    * PSL44Hz
    * Can remove this effect. Move the 24V power supply to ouutside of the PSL room. Portable1 acc moved to white laser lack.
   * IMMT1 vibration 
    * ISS cover check
    * Check the portable acc, but not detected the serious noise (structure below 40Hz), there seems no large noise structure candidate..

  * Kozakai
   * Glitch issue
    * Omicron was unstable now
    * Development the spectrogram tool
   * Pick up the requirement to PEM for the JPS meeting

  * TTanaka
   * Preparing for the PEM injection 
    * PEM injection from analysis building without KAGRA DAQ
    * Easy set, easy injection
    * Select the PC there is useful injection software, and via USB or something, we can inject remotely if we set the injector to the mine
    * Discussion about the future plan this weekend

  * Miyo
   * Seismic motion issue if there is topic

  * Okutomi
   * Shaker injection

  * Kaihotsu 
   * Vacuum pump vibration and comparison between TEAC706 and chromebook
    * Using the TEAC706 and KAGRA DA, he checked the vibration of the vacuum pump very carefully
    * Actually, there is large 312.5Hz noise. there is 315Hz in the PR2 vacuum pump instead of the 312.5Hz.
    * If you read the controller, you can check the rotation rate
  
  * Fujikawa
   * Fujimopy
    * Fujikawa+Mori
    * Extract the line peak
    * Implementing the various noises
   * Lockloss with earthquake
    * Earthquake vs lockloss
    * check by the MCF seismometer
    * He found the some earthquake make lockloss
    * Investigated the lockloss vs amplitude and source of the earthquake

  * Yuzurihara
   * Yuzu summary page comments

  * etc
