Abstract

The Japan Atomic Energy Research Institute (JAERI) has developed the advanced disk and the hollow monolithic conductors for the FER/ITER toroidal field coils. The advanced disk conductor is a cable-in-conduit conductor which consists of 324 Nb₃Sn strands. The hollow monolithic conductor has hollow cooling channels and 23 Nb₃Sn strands. The JA-FENIX sample consists of a pair of straight legs: one leg is the advanced disk conductor and another is the hollow monolithic one. The FENIX facility at the Lawrence Livermore National Laboratory (LLNL) can provide a magnetic field up to 13 T on a sample conductor of over 40 cm-length. The performance test of the JA-sample was carried out in autumn 1992. The critical current, the current sharing temperature, and the stability margin of each conductor were measured in this test. These results are presented and discussed
