Abstract (en)
[origin: WO9729493A1] The invention is directed to a low-loss superconducting magnetic coil having a relatively high Q characteristic. The coil (12) includes a superconductor tape (14), wound about the longitudinal axis of the coil, the tape including a multi-filament composite superconductor having individual superconducting filaments surrounded or supported by a matrix-forming material. The superconducting coil has a Q characteristic greater than 250, at a frequency less than 1,000 Hz, with the Q defined as the ratio of the stored inductive energy in the coil with respect to the dissipation of the coil per cycle.
