Title: Development of a Nb/sub 3/Al conductor for toroidal field coils
Abstract: Nb/sub 3/Al has potential capability in realizing a TF coil that can produce a magnetic field up to around 16 T because of the inherently high critical current at high field and less sensitivity against strains. Mass production technique of Nb/sub 3/Al strands was therefore established in 1990s and about 1 ton of strands were produced by the authors. Then, coil fabrication technique was developed and a large coil, the Nb/sub 3/Al insert, was fabricated. In addition, the prototype Nb/sub 3/Al conductor for JT-60 superconducting tokamak has already been developed. The test results of these coils demonstrate applicability of the Nb/sub 3/Al conductor to TF coil with react-and-wind method. The possibility of developing TF coils whose operating field is around 16 T seems to be promised through these successive results.
