A superconducting magnet module comprises an alternate series of abutting and coaxially aligned first and second superconductive magnet modules. The first magnet module includes a first substrate having opposed first and second faces and a bore filled with a superconductive material extending between the first and second faces. The first face is formed of an electrically conductive material and the second face is formed of an electrically insulating material. A first spiral track of the superconductive material is formed on the first face in electrical and thermal contact with the electrically conductive material. The first spiral track is melt fused to the superconductive material in the bore. The second magnet module includes a second substrate having opposed third and fourth faces. The third face is formed of an electrically conductive material and the fourth face is formed of the electrically insulating material. A second spiral track of the superconductive material is formed on the third face in electrical and thermal contact with the electrically conductive material. The modules are positioned so that the second track abuts the second face and is melt fused to the superconductor in the bore to provide the superconducting magnet with a solenoidal and monolithic superconductive current path.
The melt-fused spiral tracks provide the superconducting magnet with a quasi-helical and monolithic superconductive current path which may be tailored to have a uniform critical current capacity.
