Today's activities
Workers: Akutsu, Yokogawa, Sugimoto
- Fixed the body of the fixed stage.
- Aligned the body of the fixed stage (along with the top plate put on it) by slightly hooking up it with three slings, and screwed to the base plate.
- Aligned the top plate on the fixed stage body by slightly hooking up it with four slings and four M10 eye bolts (Hirata-san gave us), and screw to the body carefully.
Measured the tilt on the top plate; should be reported later
- Installed the BRT.
- Brought the box of the BRT close to the clean booth; did some tricky treatment to go through a narrow passage between the pillars of clean booth and the ducts on the floor; to literally "overcome" obstacles, put a plate underneath the wooden box.
- Hooked up the BRT and down into EYT, and roughly alingned, and tightened by screws.
Measured the tilt on the top plate; should be reported later
- Removed covers for each optic of the BRT.
- There were some parts where I cannot easily reach my fingers to grab the screws to fix the covers to the body of the holders.
Next plan
- 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。
