Abstract:
1. A process for continuously producing high current density HTS tape having a coating thickness in excess of 1.5 microns and a critical current in excess of 200 A per centimeter width comprising: applying a first thickness of superconductor coating to a substrate as it translates through a first deposition zone in a deposition reactor; and immediately applying an additional thickness of superconductor coating to the substrate as it translates through at least one additional deposition zone in the deposition reactor while supplying oxygen in the at least one additional deposition zone, where the substrate is impinged upon by an ion beam during applying the additional thickness of superconductor coating, separate from supply of the oxygen, wherein impingement of the ion beam improves film morphology, reduces defects, and increases current density, and wherein impingement of the ion beam is carried out on the superconductor coating in a state wherein the superconductor coating has a thickness of greater than 1.0 micron.
