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



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)



Fabrication

Early focus . . . combine the best of the best from the core programs

Exchange of coil fabrication tasks for TQ’s between FNAL and LBNL

– Improved techniques– Improved documentation

Long Racetrack program

– Technology exchange between LBNL and BNL

• Length scale-up

– Reaction

– Impregnation

– Handling



Program Implementation

• Design Studies– Provide input on magnet parameters

and lay groundwork for the program – broad range of activities

• Supporting R&D

– Wide range of technical issues related to fabrication and operational parameters

– LR, SQ, SR• Verify analysis models• Performance related issues• Materials development• Support structure development

• Materials Support

– Provide sufficient quantities of well-characterized material

– Support R&D on ultimate material

• Model Magnet R&D

– Integrate input from other three areas to produce magnets with parameters relevant to LARP goals

– TQ, LQ and HQ



Goal #1 Predictable and Reproducible Performance

• Sub-scale Quadrupoles (SQ)

– Conductor evaluation– Analysis validation

• Technology Quadrupoles (TQ)

– 90 mm aperture– Gradient > 200 T/m– Explore alternate structures

using “identical” conductor– Basis for scale-up

Goal #2 Long Magnet Fabrication

• Long Racetrack

– Coil fabrication scale-up based on well-understood sub-scale coils

– Explore scale-up of shell-based support structure

• Mirror dipole scale-up via FNAL core program

Followed by . . .

• Long quadrupole (LQ)

– 3.6 m quadrupole based on TQ cross-section



Goal #3 High Gradient in a Large Aperture

• High Gradient Quadrupole (HQ)

– Explore ultimate performance

• Increase peak field on the coil to ~ 15 T• Precursor to larger aperture

4-layer: G=280-310 T/m

Program Management

• Advisory and Support Committees

– US Executive committee

– US – CERN committee• Good communication with CERN

liaison (Meetings/letters)

– LARP Advisory Committee

– DOE reviews

– Magnet Steering Committee (MSC)

– Ad hoc reviews (external/internal membership)

• Milestones and branch points

• Gourlay/MSC

– Define program

– Prioritize

– Budget guidance

– Assign tasks to appropriate organization

• Competencies/resources

– Monitor program

• External and internal reviews

• L2’s and task managers assemble tasks to implement program



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
