摘要： PURPOSE: To prevent quenching from occurring in a conductor-type superconducting magnet by a method wherein a large number of hollow plate- like superconductors are piled up into a multi short-circuit superconductor group. CONSTITUTION: A large number of hollow plate-like superconductors 1 are piled up into a multi short-circuit superconductor group 2. The multi short-circuit superconductor group 2 is composed of a large number of short-circuit superconductor plates 1 each of thickness 1mm or so. When a current is applied to an exciting coil 3 from an outer power supply 4, a current is inductively introduced into the multi short-circuit superconductor group 2, the multi short-circuit superconductor group 2 serves as a superconducting magnet when it is made to operate in a permanent current mode. Even if quenching occurs in a part of the superconductor group 2, the other residual superconductors carry an operating current provisionally, so that quenching is prevented from occurring in the superconductor group 2 as a superconducting magnet.
