  1. LARP Magnet R&DSummary S. Gourlay for the LARP Magnet Collaboration

  2. US LARP Magnet Program Large aperture, Nb3Sn Quadrupoles for LHC Upgrade Length Scale-up High Performance Conductor Development 90 mm > 250 T/m

  3. Collaboration established Excellent progress on all major activities Technology Quads (TQ) Length Scale-up Materials Model Magnet R&D TQS01 (Test in progress) TQC01 (August) TQC02 Fab and test by end of CY06 Supporting R&D SQ-01 completed in FY04 and retested in FY05 SQ-02 recently retested at FNAL @ 1.8K Long Racetrack (LR) underway Materials Characterization of strand, cable and procurement Design Studies Relevant studies underway Status and Achievements

  4. Materials • Workhorse strand established • RRP 54/61 (successful industrial and lab use) • Vigilant monitoring and evaluation required • Still an R&D material • Conservative acceptance criteria established (Is > 2 X op) • Parallel development of ultimate material (important) • Core programs • SBIR • Conductor Development Program • Continued R&D • Measurement techniques (extracted strands) • Cabling studies/parameters • Cable testing (Ic and strain degradation)

  5. Technology Quads • Excellent first result • World’s highest gradient/bore (field) quad • Truly collaborative effort • Analysis and data unprecedented • Some deviation from original plan – but we expected that • Evaluate next step in TQ • Long Quad (LQ) start in FY07 • High Gradient Quad (HQ) • Phase in as resources allow • Important to determine limits of technology

  6. Length Scale-up • Long Racetrack (LR) • Key to early start • Focus on coil fabrication issues and tooling design • Approach shell structure scale-up • Lab integration • Incurred delays not critical (yet) • Design nearly complete

  7. New Tasks for FY07 Long Quadrupole (LQ) High Gradient Quadrupole (HQ) Engineering design Additional Long Racetrack coil SQ-03 Rad-hard insulation Cable evaluation Performance expectation “short sample” Strain degradation Small racetracks (SRK), NHMFL, FRESCA Proposed new scope Rapid-cycling Nb3Sn dipole – TAMU Fast-Ramp - BNL Measurement system Design study Proposed New Tasks and Scope

  8. LARP Magnet Program is very ambitious, but . . . Based on success of core programs Focus on the goals Effective use of resources Technical Materials Extensive materials evaluation program Priority on delivery of “workhorse” material Parametric studies Sub-scale magnets for early start on technical issues Increase number of tests Schedule Program planning takes into account some unforeseen delays and difficulties Multiple targets Early schedule for completion Can recover additional schedule slip by accepting additional risk Reassess in mid-FY06 Modify as necessary Risk and Risk Management

  9. Milestones TQ Prelim LRS-01 LRS-02 Structure decision LQ-01 HQ-01

  10. In the bank! Discuss, understand, review Understand, try again. Assessment Metric Success 200 T/m 180 T/m

  11. Summary • An excellent program has evolved over the past couple of years • We have the tools and resources for success • Off to a great start!
