Medium and Low Field HTS Magnets for Particle Accelerators and Beam Lines

High Temperature Superconducting (HTS) magnets may offer an attractive alternative to both water-cooled copper and conventional low temperature superconducting magnets in many accelerators and beam lines. With energy cost rising and conductor cost falling, HTS magnets operating in the 20-60 K temperature range are gaining renewed interest for the lower cost of ownership (capital + operation). Moreover, in a few low to medium field R&D applications, HTS magnets not only provided a better technical solution but also proved to be less expensive to build and test than the magnets made with conventional Low Temperature Superconductors (LTS). In addition, HTS magnets can tolerate large energy and radiation loads and can operate with a simpler cryogenic system. This paper will present several specific examples.
