Aluminum oxide particle strengthened niobium-tin superconducting composite wire

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.
