SHMS SC Magnet Procurement Strategy • SC Magnets will be built by contractors • In a significant departure from HMS we will provide major SC magnet components – – – Superconductor (SSC surplus) Cryo-Control Reservoir( same as HMS Design) DC Power System( same as HMS) Magnet Control System( Same as HMS) Warm Yoke Steel

SHMS SC Magnet System Plan Cryogenic Control Reservoir RFP Fixed Price Procurement DC Power System Fabricated Cryostated Magnet Ship to JLAB Magnet Control System On Site Integration & Assembly Acceptance Testing Conductor Processing Testing SC Cable Magnet Support & Alignment Warm Iron Yoke

SHMS Support Structure

Mechanical Requirements • • SHMS Minimum Scattering Angle 5. 5 degrees SHMS-HMS angle 5. 5+12 = 17. 5 degrees HMS Minimum Angle (present) 10. 5 degrees SHMS Max angle 40 degrees HMS Max Angle(present ) 85 degrees Hall C Radius at SHMS max 73 feet Fit to beam pipe at 5. 5 degrees ~ 5 mm Fit to HMS at 17. 5 degrees ~ 1 cm

SHMS Support Structure Reference Design • SHMS Support Structure Preliminary Design completed in 2007 by ALION, a local company with experience in large welded steel structures • SHMS Support Structure Reference Design(RD) Completed by ALION January 28, 2009 • RD will be the technical elements for the bid packages for the SHMS support structure. • SHMS Support Structure RD review was held in December 08 at JLAB
