Things we're NOT doing in March because we'd have to bump something else
- Top filter disassembly
Tasks that we have the necessary items to do by the beginning of March
Make box of stuff to send to Mitaka
OSEM coils and connectors for assembly.
Pico in-air adapter parts.
BS soaking cup.
Anti-feedthrough adapter parts.
- Build four geophone assemblies (Okutomi-kun has built five):
- Have most parts:
Four sets of canister parts (body, neck, head).
Five geophones.
Three circuit boards - probably more exist but need to find.
20 x M8*35 (need 4*16=64)
35 x M8*30 (need 4*8=32)
4 x Viton disks (need 4? or 8?)
123 M8 washers (need 4*24=96)
Build first geophone assembly
- Get more Cu O-rings
- Complete three more geophone assemblies (4 of them are to be closed)
- Have most parts:
Assemble more OSEMs.
- Have 6 wound coils and connectors at Kamioka (one set, for SR3).
- Have 6 more at Mitaka.
- Build OSEMs
- Characterize OSEM.
Set up SR3 and SRM racks.
Miyakawa-san gave us an empty rack for SR3 => can add boxes and do internal cabling and labels.
SR3 rack position is decided (on -X,+Y corner of SR3 cleanbooth) => can do in-air cabling from rack to assembly frame.
Miyakawa-san will soon give us an empty rack for SRM and decide position => will be able to do set-up.
- Disassemble broken top filters
Set up heavy table in SRM area (first floor, -X side) => use ladder?
Find jig and blade tensioning screw.
- Remove blades from #3 (in SRM area).
- Store #3 in box.
- Remove floor panel in SRM second floor.
- Crane #1 (in SR3 area) to SRM area.
- Remove blades from #1.
- Put test weights on table.
BF rebuild - Hirata-san + 1
Move BS Test Hang BF to tent and remove blades. (These blades are for BS-BF and will not be used again.)
Find SR-BF blades that were removed to free up a BF base for the BS Final Hang.
Move BF with tilted keystone to tent and remove blades.
Characterize all SR-BF blades and choose two similar groups.
Rebuild two filters.
- Etc
Move all SFs to cleanbooth and inspect for keystone tilt and/or other issues.
Make one set of in-air pico splitter cables (triple and double) for SRM.
- Make three in-air stepper splitter cables for SR2, SR3 and SRM. [done?]
- Soak the sapphire prisms off the dummy BS for reuse on the SRM metal mass.
- Do buoyancy calculation (see LIGO-T1100616).
- Set up SR2 Guardian.
- Install damping filters for SR2.
- Stuff to have done by other teams
- Add mushroom top to SRM tank.
Put up safety bars.
