  5. SHMS Magnet Designs

  6. SHMS Magnets Stored Energy & Weight

  7. SHMS Requirements from Optics and SC Magnet Design Margin

  8. 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

  9. SHMS SC Magnet System Plan CryogenicControlReservoir DC Power System Magnet Control System Fabricated Cryostated Magnet On Site Integration & Assembly RFPFixed Price Procurement Acceptance Testing Ship to JLAB Conductor Processing Magnet Support & Alignment Warm Iron Yoke Testing SC Cable

  10. Procurement Status of SHMS Magnets • Q1 Magnet bids under evaluation-don’t ask/don’t tell • Q1 Award plan date is March 15, 2009 • Q2Q3 & Dipole RFP released Jan 26, 2009 • Q2Q3D Bids due May 2009, Award Dec. 2009 • HB magnet design review Feb. 10, 2009 • MOU/Contract with NSCL ~ June 2009

  11. Horizontal BendDesign by NSCL/MSUWarm Iron SC “C” Magnet

  12. HB Coil Drawing and 3D CAD of Winding Tooling

  13. HB Coil Winding Tooling

  14. 1st Full HB Coil – 90 Turns

  15. Q1 Quad 3D CAD Model Cold Iron Quad Design like HMS Q1Bids are IN!!

  16. Q1 Coil winding at SMI

  17. First Phase II Q1 Coil

  18. Q1 Coil Tests

  19. SHMS Support Structure

  20. 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

  21. 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

  22. SHMS General Arrangement

  23. SHMS Support Cross Sections

  24. SHMS Structure Preliminary Assembly Plan

  25. Top View SHMS & HMS Spectrometers Dipole Q3 Q2 Q1 Bender Beamline Target HMS Spectrometer

  26. Bottom View SHMS wraps around front of HMS HMS SHMS Beamline stands

  27. Bender fit up to HMS Q1 Bender HMS Q1

  28. Q3 & Dipole fit up SHMS Dipole SHMS Q3 24” Beamline Q2 Shield House notch Beamline Stand

  29. Shield House fit up Shield House Dipole Beamline Q3 Q2 Q1 Shield House notch Bender

  30. 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!!
