  1. MICE Partial Return YokePRY Fabrication 06 November 2013 Stephen R. Plate Brookhaven National Laboratory

  2. Outline • 6-Section Design Change – update • Cost & Procurement Status • Work to complete

  3. Center sections (independent removal) Lowered Restraint bars (clear mezz, south) Previous design New design Left/right symmetry Add Hall floor (no leg splices, shorter leg) Shorter horizontal reach New leg arrangement

  4. Crossbar positions not final Tie-down bar apertures repositioned Waveguide slots to be angled upward

  5. Bolted leg-channel connections Rail is now intermittent Jacking screw for disassembly (3)

  6. 6-Section Design 4° taper L C 1807 kg 3306 kg 1380 kg 3490 kg Lighter color indicates machined areas

  7. Fabrication Cost & Procurement Status • JFE steel order (JFE, Kurashiki, Japan) • 100 mm thick main plates, 50 mm backing plates • Steel of magnetic uniformity • Material total ~$70,000 for 12 plates (8 end, 4 ctr, 8 backing plates) • Delivery: ~16 weeks • Machining • Separate vendor, to be identified • ~$2850, each plate • Framework drawings • Some dwgs. out for quotation • 3 suppliers queried • Awaiting responses

  8. Work to complete • Modifications to shielding plates • Reposition crossbars • Virostek plate extension mounts and flux leakage mitigation parts • Finalize position and size of slots for tracker waveguides (angled, not normal to surface) • Add drilled/tapped holes for bolted connections, hoist rings, crossbar mounts • Assembly and detail drawings for all of the above items • Deflection/Stress Analysis • Recheck new model in ANSYS Workbench • No surprises expected, but need verification • Structural Framework • Assembly and detail drawings for restraints bars & lower support arms

  9. BACK-UP INFORMATION

  10. Assembly Procedure(in progress)

  11. Hoist ring Install Section 1 Clearance to back of channel Machined surfaces on channel mate to pink bar NOTE: Slides 11-14 show old design, but technique remains current Hoist ring spacer provides correct tilt Section 2 is similarly installed

  12. Install Section 3 (and 4) Lower hoist rings removed; guide blocks installed (also shown on isometric, Slide #4) Plate guided into engagement during lowering

  13. Install Restraint Bars All beam-to-channel connections will also be bolted

  14. (Assembly Technique – continued) • … Install Virostek plate extensions • Install spectrometer solenoids and AFC • Build and install shielding on north side, same technique as south side • Install north/south load-sharing cross bars
