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 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.

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。
