  * 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 [[http://klog.icrr.u-tokyo.ac.jp/osl/?r=10173|klog10173]]
   * ALS, the green fiber noise
   * LAS, ISS noise hunting
   * MIF, FPMI displacement

   * 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
   * [[https://www.icrr.u-tokyo.ac.jp/~yokozawa/KAGRA_line_database/index.html|url]]

   * Lock loss study  [[attachment:PEMmtg_191029fuji.pdf]]
    * with IO guardian, compare the lock loss and no lock loss data
    * python base analysis -> root base analysis
    * Make histogram for PEMs which are placed in IMC area
    * We can find the earthquake lock loss by histogram analysis
    * Easy to find the GPS time
