Abstract
Techniques are described for a method to manufacture a magnet structure comprising superconducting coils and annular spacers comprising a filled composite filler material. Also described are superconducting magnet structures as may be manufactured by such a method.
Claims23
A method for manufacturing a superconducting magnet structure, comprising:
- winding superconducting wire to form superconducting coils;
- placing an assembly comprising the superconducting coils into a molding tool;
- introducing a filled thermosetting resin into the molding tool to impregnate the superconducting coils thereby providing a resin-impregnated structure;
- causing or allowing the filled thermosetting rein to cure;
- and
- separating the resin-impregnated structure from the molding tool to provide the superconducting magnetic structure.

A method for manufacturing a formerless, multi-coil cylindrical superconducting magnet structure, comprising:
- providing a mandrel;
- winding superconducting wire onto the mandrel in corresponding axial sections to form superconducting coils;
- providing empty axial sections on the mandrel alternately with the superconducting coils to form spacers, thereby providing an assembly;
- placing the assembly comprising the mandrel and the superconducting coils into a molding tool;
- introducing dry loose filler material into the molding tool with the assembly to occupy the empty axial sections;
- introducing a thermosetting resin into the molding tool to impregnate the superconducting coils and the dry loose filler material thereby providing a resin-impregnated structure;
- causing or allowing the thermosetting resin to cure;
- and
- removing the mandrel from the resin-impregnated structure to provide the formerless, multi-coil cylindrical superconducting magnet structure.
6 more elements
A formerless, multi-coil cylindrical superconducting magnet structure, comprising:
- superconducting coils;
- and
- axial sections of spacers comprising a filler material, each one of the axial sections being provided between each one of the superconducting coils such that each one of the axial sections alternates with each one of the superconducting coils along a length of the formerless, multi-coil cylindrical superconducting magnet structure,
- wherein the filler material and the superconducting coils are impregnated with a cured thermosetting resin.
