Patent ID: 8716188

Claim:
A superconducting article, comprising: a first stacked conductor segment having a nominal thickness t n1 , the first stacked conductor segment including first and second superconductive segments, wherein the first superconductive segment includes a first substrate, a first superconductive layer overlying the first substrate, and a first stabilizer layer overlying the first superconductive layer, the second superconductive segment includes a second substrate, a second superconductive layer overlying the second substrate, and a second stabilizer layer overlying the second superconductive layer, wherein the first and second superconductive segments are arranged so the first superconductive layer and the second substrate are towards the inside of the first stacked conductor segment and the first substrate and the second superconductor layer are towards the outside of the first stacked conductor segment; a second stacked conductor segment having a nominal thickness t n2 , the second stacked conductor segment including third and fourth superconductive segments, wherein the third superconductive segment includes a third substrate, a third superconductive layer overlying the third substrate, and a third stabilizer layer overlying the third superconductive layer, and the fourth superconductive segment includes a fourth substrate, a fourth superconductive layer overlying the fourth substrate, and a fourth stabilizer layer overlying the fourth superconductive layer, wherein the third and fourth superconductive segment are arranged so the first superconductive layers and the second substrate are towards the inside of the second stacked conductor segment and the third substrate and fourth superconductive segment are towards the outside of the second stacked conductor segment; and a joint region comprising a first splice connecting the first and third superconductive segments together and a second splice connecting the second and fourth superconductive segments together, the first splice adjacent to and bridging portions of both the first and third superconductive segments along at least a portion of the joint region, the second splice adjacent to and bridging portions of both the second and fourth superconductive segments along at least a portion of the joint region, the joint region having a thickness t jr , wherein t jr is not greater than at least one of 1.8t n1 and 1.8t n2 .
