US LARP Magnet Program Large aperture, Nb 3 Sn Quadrupoles for LHC Upgrade High Performance Conductor Development Length Scale-up 90 mm > 250 T/m LARP DOE Review June 13, 2006 S. Gourlay

Status and Achievements • • Collaboration established • Excellent progress on all major activities Model Magnet R&D — TQS 01 (Test in progress) — TQC 01 (August) — TQC 02 Fab and test by end of CY 06 • Supporting R&D — SQ-01 completed in FY 04 and retested in FY 05 — SQ-02 recently retested at FNAL @ 1. 8 K — Long Racetrack (LR) underway — Technology Quads (TQ) — Length Scale-up — Materials • Materials — Characterization of strand, cable and procurement • Design Studies — Relevant studies underway LARP DOE Review June 13, 2006 S. Gourlay

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 ultimaterial (important) — Core programs — SBIR — Conductor Development Program • Continued R&D — Measurement techniques (extracted strands) — Cabling studies/parameters — Cable testing (Ic and strain degradation) LARP DOE Review June 13, 2006 S. Gourlay

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 FY 07 • High Gradient Quad (HQ) — Phase in as resources allow — Important to determine limits of technology LARP DOE Review June 13, 2006 S. Gourlay

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 LARP DOE Review June 13, 2006 S. Gourlay

Proposed New Tasks and Scope • New Tasks for FY 07 — Long Quadrupole (LQ) — High Gradient Quadrupole (HQ) • Engineering design — Additional Long Racetrack coil — SQ-03 — Rad-hard insulation — Cable evaluation • Proposed new scope — Rapid-cycling Nb 3 Sn dipole – TAMU — Fast-Ramp - BNL • Measurement system • Design study • Performance expectation – “short sample” – Strain degradation » Small racetracks (SRK), NHMFL, FRESCA LARP DOE Review June 13, 2006 S. Gourlay

Risk and Risk Management • • Schedule — Program planning takes into account some unforeseen delays and difficulties LARP Magnet Program is very ambitious, but. . . • Multiple targets • Early schedule for completion • Can recover additional schedule slip by accepting additional risk — Based on success of core programs — Focus on the goals — Effective use of resources • Technical • Reassess in mid-FY 06 — Materials — Modify as necessary • 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 LARP DOE Review June 13, 2006 S.
