FENIX experimental results of large-scale CICC made of bronze-processed Nb/sub 3/Sn strands

The Fusion Engineering International Experiments (FENIX) Test Facility has successfully completed the testing of a pair of Nb/sub 3/Sn cable-in-conduit conductors developed by the Japan Atomic Energy Research Institute. These conductors, made of bronze-processed strands, were designed to operate stably with 40-kA transport current at a magnetic field of 13 T. In addition to the measurements of major design parameters such as current-sharing temperature, FENIX provided several experiments specifically designed to provide results urgently needed by magnet designers. Performed experiments include measurements of ramp-rate limit, current-distribution, stability, and joint performance. This paper presents the design and results of these special experiments.<
