Patent ID: 8229528

Claim:
A superconducting coil, comprising: a plurality of windings, wherein each winding comprises at least one superconducting segment having an exposed area containing a granular superconducting substance having a first element and a second element; and a junction electrically connecting at least one superconducting segment of one winding to at least one superconducting segment of another winding, said junction being formed by a granular precursor substance that is reacted with the first element and the second element to form the same granular superconducting substance as that contained in said superconducting segments thereby coupling the granular superconducting substance of the exposed area of the at least one superconducting segment of the one winding to the granular superconducting substance of the exposed area of the at least one superconducting segment of the other winding, wherein said exposed areas are positioned to face each other.
