Today's activities

Workers: Akutsu, Yokogawa, Sugimoto

  • Brought an extension cable drum to EYT. Connected to a wall outlet there, and the cable was lined via ceiling of the clean booth with help by Tanioka-kun.
    • The drum was from the computer room in the tunnel; Miyakawa-san kindly allowed us to bring it.
  • Brought many things from the AOS cabinet in the center
    • a scissors, a cutter, a hex-wrench set, a combination wrench set

    • four clean slings (thanks to Hirata-san); need to take back to VIS

    • a round bubble leveler, a Shinwa's blue level, an Obishi's level AS102 524A

    • レーザー墨出器（GW-ATCのラベルあるもの）と同じく三脚。WAB作業をやってたIYCからもってきた。
    • Vectra alpha 10 (from the stock)
    • Ethanol
  • Protected the side flanges with Nitto's white sheets and tapes.
    • And with Seiden-F as well.
  • Checked the tilt of the base plate in EYT

    • Within 0.4mm/m; see here.

  • Hooked up a fixed stage from the wooden box...
    • First we tried to sling outside of the stage with two sets of two combined slings, but seemed it was dangerous as the slings tended to get slide...
    • Then tried three combined slings to hook each 120 deg angles and this worked well.

    • The chain block was bullshit; it is so dirty that my gloves got black after the work. Should be replaced with the one dedicated for clean use.

  • Put the stage roughly on the base plate; will be aligned later.

Next plan

  • Locate the stage on the base plate within XXX tilts.
  • Measure the height with a laser leveler?
  • Locate the BRT on the stage base on XXX as references.
  • Make GPT on the optical table
  • Make a model to drive signals from the TMS
  • Check the response of the TMS by swinging BS, PR2, PR3... etc... with commissioning people
  • Endのend用のフランジとりつけ。たぶん最後のほうで。
  • そこのフランジにとりつける透過光用ビューポート。まだ柏にあるはず。
  • 外側の光学定盤の上の取り回しを考えよ。

Wanted!

  • Wrenches! Small and big.
  • Markers (black and white)

From VIS

  • Four clean slings (from Hirata-san)
