Abstract :
A high-performance ohmic-heating (OH) magnet designed for the Confinement Physics Research Facility (CPRF) at the Los Alamos National Laboratory is described. The magnet has an outside radius at its throat of 1.00 m and consists of two zones: a central hour-glass-shaped coil, and an outer coil gallery of trimming coils. At maximum current, the maximum current density is 40 A/mm2, at which point it generates 38.32 W, single swing (or 76.6 W, double swing), and generates a central field of 17.37 T. The maximum von Mises stress is 408.6 MPa. The magnet stores 637 MJ with a time constant of 8.30 s.
