Introduction
As the LHC nears completion, there is increased interest in future improvement of the accelerator complex
New magnet technology, based on Nb3Sn will be a key element in any upgrade scenario
– Challenging performance parameters• Aperture: > 90 mm
• Gradient: ~200 T/m
– Operating in a high radiation environment
Improved LHC and new technology for future applications

Magnet Program Goals
Provide options for future upgrades of the LHC Interaction Regions
“Demonstrate by 2009 that Nb3Sn magnets are a viable choice for an LHC IR upgrade”
(Developed in consultation with CERN and LARPAC)
– Focus on major issues: consistency, bore/gradient (field) and length1.
1. Predictable and reproducible performance
SQ and TQ series (1 m, 90 mm aperture, Gnom > 200 T/m, Bcoil > 12 T)
2. Long magnet fabrication
LR and LQ series (4 m, 90 mm aperture, Gnom > 200 T/m, Bcoil > 12 T)
3. High gradient in large aperture
HQ series (1 m, 90 mm aperture, Gnom > 250 T/m, Bcoil > 15 T)

R&D Approach
The initial program is structured around the issues related to development of a technology base necessary to meet LARP requirements
Program is based on recent progress in the core programs
LARP augments continuing work in core programs with focused development on LARP specific issues
Main areas of focus: Conductor/cable, length scale-up, support structures, fabrication techniques

LARP Magnet R&D Program - S. Gourlay 7
Materials R&D
• Development requires constant
monitoring by LARP materials group
– Strand R&D
• Heat treat studies/strand characterization
• Extracted strand studies in support of cable work
– Cable R&D
– Conductor Procurement
• Close ties with DOE Conductor Development Program (CDP)
– CDP has been instrumental in getting LARP started
• Developed and provided high performance material
• Continued R&D (high risk development outside LARP)
Two goals for the Materials group
Provide “workhorse” material for magnet program
Support R&D program for development of future LARP material(augmented with significant core
program support)

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 budget in mid-FY06– Submit modified proposal
