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

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

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

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!
