Patent ID: 6943656

Claim:
A superconducting magnetic coil, comprising: a first coiled superconductor tape coiled about a coil axis, the first coiled superconductor tape comprising: a superconductor layer; and an electrically conductive layer having a surface forming an inner surface of the first coiled superconductor tape, the inner surface of the first coiled superconductor tape facing the coil axis of the first coiled superconductor tape; and a second coiled superconductor tape coiled about a coil axis, the second coiled superconductor tape, comprising: a superconductor layer; and an electrically conductive layer having a surface that forms an outer surface of the second coiled superconductor tape, the outer surface of the second coiled superconductor tape facing away from the coil axis of the second coiled superconductor tape, wherein the first and second coiled superconductor tapes are configured so that inner surface of the first superconductor tape is adjacent the outer surface of the second superconductor tape.
