TESTING OF ITER PROTOTYPE CABLE-IN-CONDUIT CONDUCTORS IN THE FENIX FACILITY

The Fusion ENgineering International experiment (FENIX) Test Facility has been operational since 1991 at the Lawrence Livermore National Lab oratory for testing the International Thermonuclear Experimental React or (ITER) prototype conductors. These conductors are designed to opera te stably with transport current of more than 40 kA at a magnetic fiel d of 13 T. The FENIX facility consists of four magnet sets that are co nfigured to allow easy access to the 40-cm high-field region with a te st cross-section area of 10 15 cm2. FENIX provides test conditions t hat closely simulate many of the ITER magnet operation modes. Performe d experiments include measurements of critical current, current-sharin g temperature, forced-flow properties, stability, joint performance an d cyclic fatigue effects. This paper describes the design and performa nce of these experiments.
