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

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

Conclusions• SHMS SC Magnet designs are sound, reviewed and
procurement has started• JLAB is a partner in the SHMS Magnet fabrication Superconductor, Cryogenic Interface, Iron Yokes DC systems and PLC based controls.• SHMS Support Structure Reference Design is complete detail design and fabrication begins FY10• Since we haven’t spent a dime yet We are still On time and On budget!!
