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.
  • Geophone 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.

• 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.

  • 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.
