- Rubbers(Somiya): メクラブッシュ検査成績書.pdf
- Stack recovery policy :
- Change all rubbers inside bellows with harder rubbers.
- Preparation of rubbers and some parts for replacement (R.Takahashi-san)
- Change all thick head bolts to thin head bolts
- Do we have many such bolts? (R.Takahashi-san)
- Questions
- The optical table surface height can be set at the same level as before?
--> Just adjust the optical table height adjuster bolts?
- The whole optics will rotate as a whole compared with before?
--> It can happen because the previous sit-on situation cannot always be realized again after each stack weight masses can be separated with each other. If so, all optical axis should be adjusted again in the OMC area?
- The optical table surface height can be set at the same level as before?
- Change all rubbers inside bellows with harder rubbers.
- Logistic issues
- Where should be opened?
- Bellows duct with TMP should be removed for the final adjustment?
- If so, it needs temporal stocking space as before.
- Bellows duct with TMP should be removed for the final adjustment?
- Optical table suspension
- todo list before suspension
- Cables disconnection
- OMC stage lock and some covering? FC should be applied on the OMC mirrors?
- fragile PZT cables
- OFI removal for keeping I-bolts setting?
- OMMT1, OSM Mirror, and IM fixing
- Covering for all with something or put floor KOACHs at both sides?
- How to suspend the whole optical table
