Cryogenic system including hybrid superconductors
One or more superconducting strands are separated from a matrix of normally conducting material by a high resistance barrier layer of German silver. This may take the form of a cylindrical shell of German silver, either partly or completely enclosing a core comprising one or more strands of superconducting material, or a composite of superconducting and normally conducting strands. The barrier may comprise a German silver layer sandwiched between a pair of layers of normally conducting material, such as copper. An alternative embodiment comprises a matrix of copper or other low resistance metal in which are embedded superconducting strands in a substantially parallel array separated by laminae of German silver. After correduction and twisting, superconductor wires or composites, formed to include German silver barrier layers, may be used as superconducting coils in cryogenic systems.
