A superconducting magnet includes a coil support structure comprising a body formed of a generally-cylindrical wall. The body includes at least a pair of surfaces facing inwardly of said body, each being of generally-cylindrical shape and each being adapted to abut the radially-outer surface of a respective one of a pair of ring-shaped, superconductive coils. The support structure comprises a material such as aluminum which is adapted to shrink around the coils as the body and coils are cooled to a cryogenic temperature, so as to provide interference fits between the body and the coils. To prevent movement of the coils towards each other due to magnetic attraction forces therebetween, the body includes a pair of shoulders extending inwardly from respective adjacent edges of the pair of inwardly-facing surfaces. The shoulders are adapted to abut confronting surfaces of the pair of coils to prevent the coils from moving towards each other.
