Status and Achievements
• 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

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)

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

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 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

Risk and Risk Management
• 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
