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

• 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.
