VIS Type B BS Near Term To-Do List
Every Week
Facilities
- Vacuum and roll floor.
- Wipe ladders.
- Tidy tools, parts.
Get stuff from ../WishList
2017-08-21
Design/Documentation/Planning
- Update BS Install Procedure with screenshots from new on-assembly-frame 3D CAD.
Main Assembly
Wrap new IM bottom ballast masses (Mozumi).
Install new IM masses.
Set up optical level.
Adjust IM ballast mass to give desired roll/pitch/vertical.
Level BF.
Cable BF LVDT, test and calibrate.
Adjust top of IRM to level.
Install IRM side panels.
Install IRM OSEMs.
Cable IRM OSEMs and test.
Adjust IRM and IRM OSEMs to get good alignment of IRM OSEMs and IM-IRM stops.
- Add extra ballast mass to BF.
- Add BF cap but don't anchor cables.
- Cable and test BF cap picos.
- Lift BF/IRM/IM/RM/BS and weigh.
- Adjust BF ballast if necessary.
- Crane in SF.
- Hook up BF/IRM/IM/RM/BS.
- Route cables up to SF.
- Adjust BF ballast if necessary.
Time permitting
- Lay more new in-air cabling.
Real BS Hang Tasks
Major Tasks

- Get pico drive screens fixed (Miyo-kun)
Final ballast mass production for BF and SF (Hirata-san).
Design of receptacles for rods with 8 mm heads.
Possible rebuild of BF
Set up build/test stand for filters.
Get filter test weights.
Find spare BF blade(s).
- Reclean stuff:
- PI (remove Kapton tape etc, etc).
- LLB damper stuff, especially Cu segments.
- Calibrate SF LVDT.
- Calibrate PI vertical LVDT.
- Set yoke on PI vertical LVDT (if necessary).
- Calibrate PI horizontal LVDTs.
Minor Tasks
Mechanical
