== Weekly PEM meeting ==
 * 2019/10/01(Tue) 17:00-(JST)
 * Regular meeting meeting 
 * Web meeting with Zoom2 ([[https://zoom.us/j/6676627462|Zoom2]])

=== Agenda ===
　
 * General issue

  * Interferometer status
   * Several morning runs were held. They are silent run after the IFO commissioning.
    * We can use the PEM injection and calibration line study in future
    * 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
    * Current urgent noise

  * 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?)
   * 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]], [[attachment:peak.txt|list]]
    * ALS, the green fiber noise
    * LAS, ISS noise hunting
    * MIF, FPMI displacement
    * VIS, Around the OpLev
    * --(SR3, serious 17Hz noise investigation)--
    * Wide 44Hz noise
    * BS , Serious 90Hz noise investigation

  * 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
   * Power supply, duct vibration, instruments
   * Tentative : Magnetic field and its injection

  * Virgo visiting [[https://github.com/gw-pem/kagra-pem/issues/158|github]]
   * We will start the discussion to visit Virgo at October
   * Washimi, Sugimoto(noise huntung with portable PEM)
   * Virgo-KAGRA meeting -> Tomorrow
   * 9/29-10/13

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