Summary

• Design is continuing Completed = primary beamline (choppers, guides, shielding) Current = drum shield system Future = sample stage, detector vessel, 3He polarization analyzer

• Procurements = CVI, BSI, T0 chopper, Heusler crystals, (A&E drawings for building)

• Installed = CVI, BSI, 6-15m poured in place
