AbstractNext generation fusion reactors such as the Next European Tokamak (NET) and the International Thermonuclear Experimental Reactor (ITER) have design targets for the conductor performance in their superconducting coils. These coils require high fields and must tolerate both AC and DC conditions. There are a range of superconductor configurations (monolithic, cable in conduit) and materials (Nb3Sn, NbTi) that are candidates for the conductors. This report quantifies the performance of these candidates in the expected environment of the NET/ITER coils, and shows that Nb3Sn cable in conduit type conductors can be expected to satisfy the present design targets of NET/ITER.
