Patent ID: 8176620

Claim:
A method of manufacturing a superconducting composite wire, comprising: a. providing a plurality of niobium rods; b. providing a first plurality of aluminum oxide nano-particle reinforced copper tubes; c. inserting each of said plurality of niobium rods into one of said first plurality of aluminum oxide nano-particle reinforced copper tubes to form a plurality of first assemblies; d. swaging and drawing each of said plurality of first assemblies to form a plurality of DSC-1Nb hexagonal wires; e. providing a second plurality of aluminum oxide nano-particle reinforced copper tubes; f. inserting each of said plurality of DSC-1Nb hexagonal wires into one of said second plurality of aluminum oxide nano-particle reinforced copper tubes to form a plurality of second assemblies; g. swaging and drawing said plurality of second assemblies to form a plurality of DSC-61Nb hexagonal wires; h. providing a plurality of tin rods; i. providing a third plurality of copper tubes; j. inserting each of said plurality of tin rods into one of said third plurality of copper tubes to form a plurality of third assemblies; k. deforming each of said plurality of third assemblies to form a plurality of Cu-1Sn hexagonal wires; l. providing a piece of niobium foil; m. providing an additional copper tube; n. bundling said plurality of Cu-1Sn hexagonal wires together to form a core; o. arranging said plurality of DSC-61Nb hexagonal wires around said core; p. wrapping said piece of niobium foil around said plurality of DSC-61Nb hexagonal wires; q. placing said core, said plurality of DSC-61Nb hexagonal wires, and said piece of niobium foil into said additional copper tube to form a fourth assembly; and r. drawing said fourth assembly to create said superconducting composite wire.
