Abstract:
A high temperature superconducting article, comprising:a first high temperature superconducting component having first and second ends;a layer of a first solder material, a portion of the solder layer attached to at least a portion of the first high temperature superconducting component;a second high temperature superconducting component having first and second ends, at least a portion of the second high temperature superconducting component attached to a portion of the solder layer; andat least one protective layer connected to the first and second high temperature superconducting components,wherein the portion of the first high temperature superconducting component attached to the solder material and the portion of the second high temperature superconducting component attached to the solder material form an overlap segment having a critical current at least 80% of the lesser of critical currents of the first and second high temperature superconducting components, the overlap segment critical current being measured over an article length at least 100 times the length of the overlap segment, where critical current is determined using a 1 .mu.V/cm criterion.
