Magnet Concept

Use pieces from existing (but dismantled) SM12 Magnet– This was the large dipole used by E866 and predecessors

Design coils to minimize the need to cut existing iron Decrease nonBend aperture

– to match downstream acceptance– Save on Amp-Turns

Tapered pole pieces

Copper Beam dump (either modified from E866/SM12 or new)

Graded hadron absorber within aperture of magnet (Copper, Carbon, Polyethylene)

Budgetary Estimate: Coil Fabrication

Contacted 5 possible vendors in Fall 2004 for budgetary estimates based on preliminary designs—4 vendors responded by January 2005

Revisited estimates with 3 of 4 vendors for this review (Oct-Nov 2006)

Coils: Fabrication time

Schedule based on longest lead-time vendor: – Sigma Phi: 10 Months with conductor available 4 months before Sigma Phi: 10 Months with conductor available 4 months before

deliverydelivery– Everson Tesla: 18-22 week (5 months)– Alpha Magnetics: no estimate

Requested Budget—purchase coils over two years:– FY2007:

• Bid and contract for coils• Purchase tooling

– FY2008 (starting in Jan 2008)—this is delay is the critical path itemthis is delay is the critical path item:• Purchase conductor• Fabrication of coils

Conclusions

Design of magnet is underway Sufficiently advanced enough to obtain reasonable budgetary

estimates on coil fabrication from vendors Both budget and time line are based on conservative estimates
