FENIX EXPERIMENTAL RESULTS OF LARGE-SCALE CICC MADE OF BRONZE-PROCESSED NB3SN STRANDS

The Fusion ENgineering International eXperiments (FENIX) Test Facility recently has successfully completed the testing of a pair of Nb3Sn ca ble-in-conduit conductors developed by the Japan Atomic Energy Researc h 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 paramet ers such as current-sharing temperature, FENIX provided several experi ments specifically designed to provide results urgently needed by magn et designers. Performed experiments include measurements of ramp-rate limit, current-distribution, stability, and joint performance. This pa per presents the design and results of these special experiments.
