AARD Sub-panel at Fermilab Feb , 2006 LARP Magnet R&D Program - S. Gourlay3 Introduction  As the LHC nears completion, there is increased interest in future improvement of the accelerator complex  New magnet technology, based on Nb 3 Sn 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

Gourlay4 Magnet Program Goals Provide options for future upgrades of the LHC Interaction Regions “Demonstrate by 2009 that Nb 3 Sn 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 length 1. 1.Predictable and reproducible performance SQ and TQ series (1 m, 90 mm aperture, G nom > 200 T/m, B coil > 12 T) 2.Long magnet fabrication LR and LQ series (4 m, 90 mm aperture, G nom > 200 T/m, B coil > 12 T) 3.High gradient in large aperture HQ series (1 m, 90 mm aperture, G nom > 250 T/m, B coil > 15 T)

AARD Sub-panel at Fermilab Feb , 2006 LARP Magnet R&D Program - S. Gourlay6 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

AARD Sub-panel at Fermilab Feb , 2006 LARP Magnet R&D Program - S. Gourlay7 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)

Gourlay8 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

AARD Sub-panel at Fermilab Feb , 2006 LARP Magnet R&D Program - S. Gourlay9 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

Gourlay10 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

AARD Sub-panel at Fermilab Feb , 2006 LARP Magnet R&D Program - S. Gourlay11 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

AARD Sub-panel at Fermilab Feb , 2006 LARP Magnet R&D Program - S. Gourlay12 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= T/m
