Today's activities
Workers: Akutsu, Simon, Yano, Ken Tanaka
- Checked and adjusted the height
- Firstly draw a reference line on a white tape attached to the wall of the 8K shield to easily check where is the center of duct; which was, as written in the klog above, 269mm from the top surface of the breadboard... the nominal number should be 270mm, right??
- Anyway we continued the checking and found the suspended WAB was slightly rolling, so adjusted the roll by the top stages.
Next plan
- Check the height and horizontal position of the WAB.
- Check the pitch and yaw of the WAB.
- Before moving the WAB suspension to the saving mode, attach the magnet dampers.
Wanted!
- Vertical standing ruler (or Height Gauge)
