A compound superconducting wireincludes a reinforcement portionand a compound superconductor. In the reinforcement portion, an assembly of plural reinforcement elementsare disposed. The reinforcement elementseach include plural reinforcement filamentsdisposed in a stabilizer, and a stabilizing layerat the outer periphery thereof. The reinforcement filamentseach mainly contain one or more metals selected from the group consisting of Nb, Ta, V, W, Mo, Fe, and Hf, an alloy consisting of two or more metals selected from the aforementioned group, or an alloy consisting of copper and one or more metals selected from the aforementioned group.

Compound superconducting wire and method for manufacturing the same

In a superconducting magnet system which has a superconducting coil member, a cryocooler for cooling the superconducting coil member into the superconducting state, and a current lead for supplying an electric current to the superconducting coil member, the current lead is made of a high-temperature superconducting material and is also cooled by the cryocooler into the superconducting state with the current lead kept in contact with the cryocooler.
