Abstract

A superconducting conductor assembly using high temperature materials. A double-walled tubular structure has at least one helical strip of superconductive material on the inner wall of the inside tube. Brittle, non-ductile superconducting materials may be used. A coolant, typically liquid nitrogen, is circulated between the tubes to maintain the superconductor below the critical temperature of the superconductor. A buffer layer is preferably included between tube wall and superconductor. A plurality of alternating layers of buffer and superconductor may be used.
