Abstract
A laminated superconductor wire includes a superconductor wire assembly, which includes a first superconductor insert comprising a first high temperature superconductor layer overlaying a first substrate and a second superconductor insert comprising a second high temperature superconductor layer overlaying a second substrate. The first and second superconductor inserts are joined together at their respective substrates. An electrically conductive structure substantially surrounds the superconductor wire assembly.

- an electrically conductive structure substantially surrounding the superconductor wire assembly.
A laminated superconductor wire, comprising:
- a superconductor wire insert, said insert having a length and a width, said insert comprising a high temperature superconductor layer overlaying a surface of a substrate;
- a wetting layer deposited on a surface of the substrate opposing the high temperature superconductor layer;
- and
- an electrically conductive structure substantially surrounding the superconductor wire insert, wherein the electrically conductive structure comprises:
- a first conductive strip and a second conductive strip, wherein the superconductor wire insert is interposed between and is in electrical contact with the first and second conductive strips;
- and
