Real BS Hang Tasks
Major Tasks
- Final ballast mass design/production for BF and SF (Fabian, Hirata-san).
- Get final OSEM cables (six of 1.7 m, two of 2.2 m, two of 2.4 m; Sato-san).
- Possible rebuild of BF and/or SF
- Set up build/test stand for filters.
- Get filter test weights.
- Find spare BF blade(s).
- Prepare real BS:
- Coordinate with Hirose-san.
- Book transport of mirror (Kashiwa to KAGRA)
- Gather mirror box, gluing supplies, prisms, magnets, new flags, new flag jigs.
- Solve problem of lack of scribe line on one side of BS (Mark, Hirata-san).
- Organize cleanroom gear for Kashiwa trip(s).
- Put magnets in flags.
- Glue flags/prisms at Kashiwa.
- Reclean stuff:
- PI (remove Kapton tape etc, etc).
- LLB damper stuff, especially Cu segments.
- Try rearranging arc weights to make room for magic wand (3D CAD or actual weights; Fabian or Hirata).
- If needed based on previous, order longer threaded rods for arc weights on PI (Hirata).
- Calibrate PI vertical LVDT.
- Set yoke on PI vertical LVDT (if necessary).
- Calibrate PI horizontal LVDTs.
Minor Tasks
Mechanical
- Get clean bag laundered.
- Swap out temporary ballast mass in BF, SF.
- Return/replace borrowed parts:
- Lock washers for LBB dampers
- Temporary ballast mass (dog clamps) in BF.
- Wide-mouth OSEMs from RM to Akutsu-san
- Adjust height of crossbars below BF.
- If possible, fix galled pole in BF level of EQ stop.
- Swap in new F0-SF maraging rod (with 8-mm heads) and new receptacles to match.
- Check inside SF for lost ruler.
- Tighten PI yaw return spring.
- Get Cu O-rings for feedthroughs.
Electrical
