=== Agenda ===
 
 * General issue

  * Interferometer status
   * Now, we can lock the interferometer stably
   * ISS(Intensity Stabilization System) was implemented, better sensitivity
   * Long silent run at 2nd Nobember ([[http://klog.icrr.u-tokyo.ac.jp/osl/?r=11312|klog11312]])
   * See the detail in [[http://gwwiki.icrr.u-tokyo.ac.jp/JGWwiki/KAGRA/Subgroups/DET/RUN/MORNINGRUN2019|url]]
   * Silent run -> Some excitation(including calibration line) -> PEM injection -> Hardware injection

 * PTEP paper
  * [kagra 03133]
  * KAGRA Overview papers
  * Overview of KAGRA : (3) Detchar, calibration, physical environment, data quality

 * Next F2F meeting
  * RESCEU
  * 4th and 5th Dec., 2019
  * 1 slot Washimi-san will have a talk
  * If you plan to write master/doctor thesis, please let me know

 * Chrome Book project (Portable PEM researcher)
  * http://gwwiki.icrr.u-tokyo.ac.jp/JGWwiki/KAGRA/Subgroups/PEM/Portable
  * We prepared two PEM Chromebook
  * Start writing paper (PTEP?)

 * 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), FFU, Noise search

 * Database for the KAGRA characteristic lines
   * [[https://www.icrr.u-tokyo.ac.jp/~yokozawa/KAGRA_line_database/index.html|url]]

 * Visitors from LV
   * Anamaria from Livingston : 18 - 29 Nov.
   * Federico, Irene, Camilla (input optics) + Francesca from Virgo : 11/18-12/7 (2 weeks@KAGRA, 1 weeks@NAOJ)

 * Each progress

  * Yokozawa
   * Current serious noises
    * 24Hz noise (100V AC + AA?)
    * MICH control noise
    * Coherent with ITMX MN YAW
    * Coherence with ITMY TM PIT
   * Daily summary page
