Collar, yoke, skin • Collar: • RFQ’s, one for EDM and the other for stamping, both using 316 series stainless steel have been sent out and replies received • vendor visit is completed and vendor was selected to make collar laminations for next series of 2 m magnets • First article inspection – January 2013 • Procurement – February 2012 • Yoke laminations - available • Skin - fabrication of 2 m long bolted shell assembly parts has begun.

12. Design work • Collar shoe thickness increased, drawing revised. • Lift features added to collar design, revised drawing in progress. • Adapter for collar lifting fixture to lift collared coil assembly is in progress. • Coil end part revision based on lessons learned for future coils is on hold. • 2-in-1 yoke design has proceeded as far as it can. Waiting for FEA in order to create and release drawings for the mechanical model. • 2m bolt on skin contact tooling design is in checking and nearly complete. • Long coil winding and curing design is at a very low priority. • Long coil reaction and impregnation assembly drawings continue is at a very low priority.
