ABSTRACT:
A superconducting apparatus is provided with windings having superconducting wires wound in a plurality of turns, and a cryostat housing the windings so as to cool the windings in a superconducting state. The superconducting wires disposed at the outer and inner peripheral areas of the windings are selected to be highly stabilized superconducting wires such that, even if frictional heat is conducted towards the windings, the highly stabilized superconducting wires are very less quenched and in turn the possibility of the quenching of the overall windings is extremely low. Further, good heat conductors are provided on the radially outer and inner of the windings. Frictional heat which flows towards the windings is transmitted into the good heat conductors in the circumferential direction, and is dissipated midway during the heat conduction. As a result, the introduction of the frictional heat into the windings is avoided and in consequence no quenching occurs in the superconducting wires. This enables the overall windings to be prevented from being quenched.
