Abstract

PURPOSE:To prevent the Joule heat from being generated by a method wherein a high-temperature superconducting material is attached to both end parts of a coil to which a superconducting coil composed of an ordinary superconducting conductor and electric-current leads are connected. CONSTITUTION:High-temperature superconducting materials (composed of an oxide of Y, Ba and Cu or the like) 12 are attached to peripheries of both end parts of a superconducting coil 2 composed of an ordinary superconducting conductor. Even if a temperature at both end parts 2a of the coil is increased due to the penetrating heat from electric-current leads 11 or due to a drop in a cooling effect when a liquid level of liquid helium 4 is lowered and both end parts become a normal conducting state, the high-temperature superconducting material remains in a superconducting state because its critical temperature is high. As a result, an electric current flows to the high- temperature superconducting material whose electrical resistance value is zero, and the Joule heat is not generated. By this setup, even if the temperature at both end parts 2a of the coil is increased, the high-temperature superconducting material remains in the state; the Joule heat is not generated; the coil as a whole is not set to the normal conducting state.
