Development of the prototype conductors and design of the test coil for the Fusion Experimental Reactor

For the Prototoroidal Coil project, a prototoroidal coil will be fabricated and tested electromagnetically and mechanically under conditions similar to the operating conditions of the toroidal coils of the Fusion Experimental Reactor (FER). Three types of 30-kA, 12-T, force-cooled conductors have been developed as the prototype conductors of the prototoroidal coil. Trial fabrication of these conductors and evaluation testing of their elements are under way. Design of the prototoroidal coil and its background field coil system, which consists of two LCT (Large Coil Task) coils and two LCT backup coils, is also in progress. >
