Patent ID: 7015779

Claim:
A superconducting magnet comprising: a plurality of superconducting coils, said coils being impregnated with epoxy and nested within each other, an innermost one of the nested coils having a bore therethrough defining a bore width of the magnet, said bore width being greater than approximately 100 millimeters, said nested coils being electrically connected in series and cooled to an operating temperature less than approximately 4 degrees K; and an integral external reinforcement on at least one of the superconducting coils, said reinforcement comprising an external reinforcement wound on the at least one superconducting coil before said coil is impregnated with epoxy, said reinforcement and said at least one of the superconducting coils being impregnated in the epoxy together for providing structural reinforcement to the magnet in both radial and axial directions.
