FAULT CURRENT LIMITING SUPERCONDUCTING COIL

摘要

A superconducting coil (10) includes a first superconductor (18) formed of an anisotropic superconducting material for providing a low-loss magnetic field characteristic for magnetic fields parallel to the longitudinal axis of the coil (10) and a second superconductor (22) having a low loss magnetic field characteristic for magnetic fields perpendicular to the longitudinal axis of the coil (10). The first superconductor (18) has a normal state resistivity characteristic conductive for providing current limiting in the event that the superconducting magnetic coil (10) is subjected to a current fault.
