1. A method for manufacturing a formerless, multi-coil cylindrical superconducting magnet structure, comprising:
providing a mandrel;
providing temporary locating features protruding from a radially outer surface of the mandrel to define axial sections, each one of the axial sections being respectively configured to carry superconducting coils and annular spacers of composite filler material;
winding superconducting wire onto the mandrel in corresponding ones of the axial sections to form respective superconducting coils;
placing an assembly comprising the mandrel, temporary locating features, and superconducting coils, into a molding tool;
introducing a thermosetting resin into the molding tool to impregnate the superconducting coils and to provide a composite filler material in other corresponding ones of the axial sections to form annular spacers;
removing from the molding tool a structure including (i) the formerless, multi-coil cylindrical superconducting magnet structure, and (ii) the mandrel; and
removing the mandrel from the structure to provide the formerless, multi-coil cylindrical superconducting magnet structure.
