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

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 Bend Design by NSCL/MSU Warm Iron SC “C” Magnet

12 HB Coil Drawing and 3D CAD of Winding Tooling

13 HB Coil Winding Tooling

14 1 st Full HB Coil – 90 Turns

15 Q1 Quad 3D CAD Model Cold Iron Quad Design like HMS Q1 Bids 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 Bender Q1 Q2 Q3 Dipole Target Beamline HMS Spectrometer

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

27 Bender fit up to HMS Q1 Bender HMS Q1

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

29 Shield House fit up Shield House Beamline Shield House notch Dipole Q3 Q2 Q1 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!!
