Patent ID: 7365271

Claim:
A superconducting article, comprising: a substrate having a length, a width and a longitudinal direction, wherein the length is at least about 100 meters, the length is greater than the width, and the longitudinal direction extends along the length; and a layer of superconductor material overlying the substrate, said layer comprising a plurality of superconductor strips and a plurality of superconductive bridges coplanar with the plurality of superconductive strips, wherein (i) the plurality of superconductor strips extend along a longitudinal direction, the superconductor strips comprising a first, a second, and a third superconductor strips extending parallel to each other along the longitudinal direction, being coextensive with each other along at least a portion of the length, and the first and second superconductor strips and the second and third superconductor strips being spaced apart from each other along the width by a first and a second gap respectively, the first and second gaps having a length extending parallel to the longitudinal direction; and (ii) the plurality of superconductive bridges electrically connecting at least the first, second, and third superconductor strips with each other and spanning the first and second gaps, the plurality of superconductive bridges being provided such that at least one superconductive bridge is present per 10 meters of length of the substrate, wherein the substrate has a dimension ratio of not less than about 10.
