Abstract

Abstract A superconductor structure is disclosed in which a plurality of superconductive assemblies are provided with at least one cooling arrangement. The superconductive assemblies consist of superconductor components and a stabilizing conductor, with at least a portion of the stabilizing conductors in the structure being provided with cooling passages. A cooling arrangement is enclosed between adjacent superconductive assemblies. The assemblies are preferably insulated from each other to prevent eddy current flow and may be joined by resistors or diodes connected across the ends of the superconductor components.
