Abstract: A superconducting article and method of fabrication are provided. The superconducting article includes a superconducting structure, which includes a superconducting conductor and multiple discrete overlay regions of higher heat capacity than the superconducting conductor. The multiple discrete overlay regions are disposed along a length of the superconducting conductor, in thermal contact with the superconducting conductor, and positioned to define a heat modulation pattern along the length of the superconducting structure. The multiple discrete overlay regions create a temperature distribution favorable to transition of the superconducting structure under load from a normal resistive state to a superconductive state by facilitating formation of a continuous superconducting path along the length of the superconducting structure. In one implementation, the multiple discrete overlay regions are multiple island regions periodically disposed adjacent to opposing first and second edges of the superconducting conductor along the length of the superconducting conductor.

Abstract: In accordance with the present invention, modular corona shields are employed in a HTS device to reduce the electric field surrounding the HTS device. In a exemplary embodiment a fault current limiter module in the insulation region of a cryogenic cooling system has at least one fault current limiter set which employs a first corona shield disposed along the top portion of the fault current limiter set and is electrically coupled to the fault current limiter set. A second corona shield is disposed along the bottom portion of the fault current limiter set and is electrically coupled to the fault current limiter set. An insulation barrier is disposed within the insulation region along at least one side of the fault current limiter set. The first corona shield and the second corona shield act together to reduce the electric field surrounding the fault limiter set when voltage is applied to the fault limiter set.
