  • Report from Extended Chief meeting on Jan. 22nd (Hayama)
    • Experiment after bKAGRA phase1 run will start around the end of April (on Apr. 30th).
    • 5th and 6th day will be assigned to PEM injection (If the bKAGRA phase1 run finish on Apr. 29th, they are May 4th and 5th.)
  • Recent news
    • In bKAGRA phase 1 run, only ETMY will be cryogenic. ETMX will not be cooled down.

    • Following this, how about changing our plan: Injection will be perform in ETMY although original plan is ETMX.

    • Problems
      • Rack
      • TMSとの調整。
  • Progress report from Hongo
    • Calibration of the toy pendulum system (injection target in rehearsal) has beed done.
    • We checked two demo-unit of small accelerometer (FG-142 and 2002E).
      • We will buy FG-142 in next fiscal year.
    • Miyazaki-kun, who is a new grad. student of Ando lab., has started to make analog circuits for magnetometer.
    • Magnet wire for large coil (~100 m) arrived. Large wooden bobbin will arrive in the end of Jan. (or the beginning of Feb.)
    • Connector parts for amplifier (QSC RMX5050a) arrived.
    • We obtained power supply connector used in KAGRA. However, we don't have pins.
      • Maybe we will make it in Kamioka on the first day of the rehearsal. Or will anyone who come to Tokyo (e.g. Ochi-kun's master thesis defense) kindly take the pins?
  • Progress report from Kamioka
  • Communication tool for the PEM injection: Slack (Miyo)
  • github for management of the PEM project (Miyo)
    • Can we perform project management only with pure github like this? (Nagano)
    • Is it necessary to do this under detchar repository? (Nagano)
