== Weekly PEM meeting ==
 * 2020/05/01(Fri) 14:00-(JST)
 * Regular meeting (Japanese) 
 * Web meeting with Zoom2 ([[https://zoom.us/j/6676627462|Zoom2]])

=== Agenda ===
　
==== General issue ====

 * Interferometer status
  * Two weeks observation was completed
  * Earthquakes at Kamikochi(上高地) is serious
   * Large frequency
   * Close from KAGRA. Damage to alignment
  * Now interferometer is "suspend mode"
   * No measurements
   * Keep the IMC lock
   * Check the green laser flash

 * Tasks for post-commissioning
  * [[https://docs.google.com/spreadsheets/d/1w4q8OvX9E6nkYSgshLYLoZH5yvQXHvGmL1agux8ztx0/edit?usp=sharing|post commissioning]]
   * Scattered light (One of the hammering test)
   * OMC chamber vibration RMS
   * PEM injection
   * Line noise investigation by PEM

 * PEM papers (Writer)
  * KAGRA summary paper(Yokozawa)[[attachment:PTEP_PEM_200501.pdf|pdf]]
   * Part of the KAGRA overview paper
   * PTEP (Overview of KAGRA : (3) Detector characterization, calibration, physical environment, and data quality)
    * Installation
    * Technical issue
  * Acoustic injection paper (Washimi)
   * Target journal
   * Request 3+8 hours data taking to commissioning
  * Portable PEMs (Yokozawa)
