Design and fabrication of a 14 T, Nb/sub 3/Sn superconducting racetrack dipole magnet
Most accelerator magnets for applications in the field range up to 10 T utilize NbTi superconductor and a cosine theta coil design, For fields above 10 T, it is necessary to use Nb/sub 3/Sn or other strain sensitive superconductors and other coil geometries that are more compatible with these materials. This paper describes our recent efforts to design a series of racetrack coil magnets that will provide experimental verification of an alternative magnet design philosophy, with the near-term goal of reaching a field level of approximately 14 T. The conductor and fabrication issues relevant to building high field, racetrack dipoles utilizing Nb/sub 3/Sn superconductor and a wind and react approach will also be discussed.
