TEST-RESULTS OF THE FER ITER CONDUCTORS IN THE FENIX TEST FACILITY

The Japan Atomic Energy Research Institute (JAERI) has developed the A dvanced Disk and the Hollow Monolithic conductors for the FER/ITER Tor oidal Field coils. The Advanced Disk conductor is a Cable-in-Conduit c onductor which consists of 324 Nb3Sn strands. The Hollow monolithic co nductor has hollow cooling channels and 23 Nb3Sn strands. The JA-FENIX sample consists of a pair of straight legs: one leg is the Advanced d isk conductor and another is the Hollow Monolithic one. The FENIX faci lity at the Lawrence Livermore National Laboratory (LLNL) can provide a magnetic field up to 13T on a sample conductor of over 40cm-length. The performance test of the JA-sample was carried out in Autumn 1992. The critical current , the current sharing temperature, and the stabil ity margin of each conductor were measured in this test. These results are presented and discussed.
