BF actuator coupling from L to P
- What is the dip at 0.04 Hz??
Access to BF screws from the bottom
- Make new holes on the EQ stop ring below the BF so that the screws and allen key can be inserted from the bottom.
Wire length and height
- The length of the existing wires should be checked. The height of the suspension parts should also be checked.
LVDT assembly
- Since the F7 LVDT units are heavy, some assembly jigs should be prepared. According to the assembly jigs, some of the mechanisms to adjust the LVDT position may be omitted. Protection of dropping the LVDTs should be prepared.
Schedule
- The final design check will be done in the 1st week of September 2016.
Requirement for the detailed design
- Surface treatment, Compatibility with the vacuum system should be included.
Weight
- Traverser can hang and move the 470 kg suspension. But the safety factor is not enough for the installation crane work. Some installation jigs should be prepared.

Check wire length and the height of the parts in the model (Shoda)
Add the additional holes on EQ stop ring (Saito)
Think about the LVDT assembly jigs (Shoda, Saito)
Clarify the information of the surface treatment and so on. (Shoda)
Think about the installation jigs for the Traverser protection (Saito, Uraguchi)
