  9. HEHIHB - WP1Accelerator Magnet Technology Networking activity

  10. LHC: What might be next? Radiation damage limit ~700 fb-1 • Due to the high radiation doses to which they will be submitted, the life expectancy of LHC IR quadrupole magnets is estimated ~5-7 years. • Hence, it is likely that these magnets will have to be replaced in 2013-2015, thereby offering an opportunity of upgrading LHC IR optics to improve luminosity. Courtesy of F. Ruggiero and Jim Strait • Mid-2010’s is also the earliest time frame when one can expect to need final-focusing quadrupole magnets for any of the proposed projects of linear colliders. At least one needs very strong wide final triplets. Walter Scandale - 23 February 2004 - Collège de France - Paris

  11. State of the Art in NbTi • Since the Tevatron, the most widely used superconductor is NbTi (world production: ~1500 t/year). • The LHC magnet R&D programs have shown that the limit of NbTi at 1.8 K was around 10 to 10.5 T. • Hence, to go beyond the 10-T threshold, it is necessary to change the material. Quench performance of 88-mm-aperture MFRESCA dipole magnet at CERN built by D. Leroy team. Walter Scandale - 23 February 2004 - Collège de France - Paris

  12. Beyond NbTi • High Temperature Superconductors (HTS)are not yet ready for large-scale applications requiring high current densities under high magnetic fields, and it is likely that it will take at least another decade before they become competitive (in terms of performances, yield and cost). • The upper critical field of MgB2is too low. • Nb3Alexhibits promising properties but there are serious manufacturing issues that have yet to be resolved. • At present, the only serious candidate to succeed NbTi, suitable for industrial production in the next 5 years, is the intermetallic compoundNb3Sn (world production amounts to ~15 t/year). Walter Scandale - 23 February 2004 - Collège de France - Paris

  13. The path for High-Field Accelerator Magnet R&D • A reasonable roadmap for high-field accelerator magnet development appears to be • get ready for LHC-IR upgrade in 2013-15 • (large-aperture, high-performance dipole and/or quadrupole magnets; cost is not the primary issue), • The real R&D -focussed- is here, and it will be the base for all the other possible goals • develop final-focusing quadrupole magnets for implementation in alinear collider IR in the mid-2010’s • (LHC-type quadrupole magnets in a solenoidal background field, or compact quadrupole magnets; cost is not the primary issue), • Some magnet R&D aimed at LHC energy upgrade or a VLHC in the 2020’s (high-performance, low-cost dipole). Walter Scandale - 23 February 2004 - Collège de France - Paris

  14. What do we have to do in the frame of HEHIHC? • Review if really we need this change in technology or if different IR schemes can do the job by using improved NbTi or NbTiTa (1T beyond NbTi) • Meanwhile: • revisit magnetic and mechanical designs to achieve enhanced performances with coils made from brittle conductors, • address coil cooling issue under high beam losses, • keep promoting high-performance Nb3Sn wire development (ensuring the survival of multiple suppliers around the world), • improve mechanical robustness and assess radiation hardness of Nb3Sn conductor insulation, • put into practice all of the above in magnet models and prototypes.
