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: • Gradient: > 90 mm ~200 T/m – Operating in a high radiation environment Improved LHC and new technology for future applications AARD Sub-panel at Fermilab Feb. 15 -17, 2006 LARP Magnet R&D Program - S. Gourlay 3

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. 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) AARD Sub-panel at Fermilab Feb. 15 -17, 2006 LARP Magnet R&D Program - S. Gourlay 4

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. 15 -17, 2006 LARP Magnet R&D Program - S. Gourlay 6

Materials R&D 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) • Development requires constant monitoring by LARP materials group • Close ties with DOE Conductor Development Program (CDP) – CDP has been instrumental in getting LARP started • Heat treat studies/strand characterization • Developed and provided high • Extracted strand studies in support of performance material cable work • Continued R&D (high risk – Cable R&D development outside LARP) – Strand R&D – Conductor Procurement AARD Sub-panel at Fermilab Feb. 15 -17, 2006 LARP Magnet R&D Program - S. Gourlay 7

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. 15 -17, 2006 LARP Magnet R&D Program - S. Gourlay 8

Program Implementation • Materials Support • 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 AARD Sub-panel at Fermilab Feb. 15 -17, 2006 – Provide sufficient quantities of well-characterized material – Support R&D on ultimaterial Model Magnet R&D – Integrate input from other three areas to produce magnets with parameters relevant to LARP goals – TQ, LQ and HQ LARP Magnet R&D Program - S.
