 * hgoe  * Put tags to cables partially.

 * Confirmed vertical actuation coils worked well.
   * Although Nagano said "horizontal" coils were checked, it was wrong. It was found that cable of vertical and horizontal coils were flipped.
 * Delivered mirror (three 1-inch Green Steering mirrors) were put on the desiccator.
 * Installed BRT on TMS-VIS (would be reported by Akutsu-san?)
 * We confirmed Green beam was reduced by BRT properly. Also, we could see the shadow of PDA100A which was placed in front of ETMX.

Today's activities

Workers: Akutsu, Uraguchi, K. Nagano, Hasegawa, K. Tanaka, Kita

  • Put tags to cables partially.
  • Confirmed all signals could be seen in digital system.
  • Confirmed vertical actuation coils worked well.
    • Although Nagano said "horizontal" coils were checked, it was wrong. It was found that cable of vertical and horizontal coils were flipped.
  • Delivered mirror (three 1-inch Green Steering mirrors) were put on the desiccator.
  • Installed BRT on TMS-VIS (would be reported by Akutsu-san?)
  • We confirmed Green beam was reduced by BRT properly. Also, we could see the shadow of PDA100A which was placed in front of ETMX.

Next plan

  • Connect the cables to flanges.
  • Configure the digital models properly.
    • Engage the logical channels and the assigned physical channels.
  • Install BRT on TMS-VIS.
  • Clean the sides of the optics to be installed into the vacuum chamber. (Ethanol+Acetone wiping with vectra alpha, then First Contact.) See here.

  • Detach the remaining white tapes just before closing the chamber; be noted that there are white tapes on the PEEK connectors at the inside of the flanges.
  • Torque completely the bolts which are fixing the upper and the lower base plates.
  • Insert metal gaskets before torquing the ICF203 flanges with Dsub connectors.
  • Make clean the cabling... ask to VIS??
  • Check horizontal actuation
  • Calibrate LVDT again
  • Put calibration factor of Geophones
  • Install Tome-Kanagu for Dsub in DAC0 port #4
  • Put tags to cables
  • Align BRT
  • Start to install GPT part
  • Damping of TMS-VIS

Wanted!

  • Tester!! lend from DGS or PEM??
  • M8 eyebolts for managing the dummy weight plates...
  • First contact to clean the side diameter of the optics.
  • Need a signal generator for LVDTs
  • A document for learning how to release or fix the suspended tables (by Uraguchi?).
  • Cable tags
  • IR mirrors (4 PYD-20, 3 PYD-10)
  • Tome-Kanagu for Dsub
