Title: A Hybrid HTS/LTS Superconductor Design for High-Field Accelerator Magnets

Abstract

Purpose of Research, Research Carried Out, and Research Findings: Fabricating and testing a proof-of-principle hybrid HTS/LTS common-coil dipole, and improving the field homogeneity in magnets of ReBCO tape, have advanced technology for accelerator magnets. High-strength ReBCO tape with a Hastelloy substrate has long been the preferred approach for high field magnets, because it can withstand high stresses, but was deemed impractical, primarily because its propensity to magnetize wreaks havoc with field homogeneity. The technique developed during our Phase II project shows great promise in reducing magnetization to an acceptable level. As a result, very high field magnets made with ReBCO HTS tape now may become viable for future circular colliders. We demonstrated a proof-of-principle HTS/LTS hybrid magnet. Facilitating accomplishment of this ambitious task was a magnet unique to BNL that, without the prohibitive cost of disassembly and reassembly, can accommodate coils of HTS for testing in a background field as high as 10 T. The design techniques demonstrated may reduce the quantity, and hence the cost, of expensive HTS by a factor of two or more. PBL, BNL and e2P developed a preliminary engineering design for an economical 20 T dipole magnet amenable to mass production. The design and technologymore » are likely to be useful in other areas as well; PBL is soliciting interest by other companies. The work performed has led to the award of US Patent number 9793036: “A Low Temperature Superconductor and Aligned High Temperature Superconductor Magnetic Dipole System and Method for Producing High Magnetic Fields”.« less
