Abstract
The design and fabrication principles of the first high-field insert for SULTAN are described and the results of the coil test performed in the background field of the SULTAN facility are presented. The Swiss Nb3Sn insert coil is the first of three A15 coils of SULTAN planned to demonstrate the feasibility of high-current, high-field superconductor technology for fusion devices in Europe. The forced-flow, steel-reinforced conductor is based on an external diffusion Nb3Sn cable, and is reacted before conventional fabrication of the 60-cm bore coil. During tests in the background field of SULTAN, the coil reached the design current of 6 kA without training. It could only be turned normal by raising the temperature to 7.8 K at a current of 6.5 kA. In the present single-insert configuration of SULTAN a peak conductor field of 10.5 T was reached.
