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 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 havent spent a dime yet
• We are still On time and On budget!!
