DEVELOPMENT OF A 13T-46KA NB3SN CONDUCTOR AND CENTRAL SOLENOID MODEL COILS FOR ITER

Japan Atomic Energy Research Institute (JAERI) is developing the outer module of the central solenoid (CS) model coils. The Nb3Sn strands an d cables for the outer module were almost completed. The winding and t he heat treatment technique were established by the trial fabrication. The design of the conductor joint was already finalized by the full s ize sample test. The first layer of the 8-layer module was wound with enough accuracy by using a two-conductor-in-hand technique. The CS mod el coil will be completed and tested in 1998.
