Process for making a superconducting magnet for particle accelerators

This patent describes a method of constructing a particle accelerator having superconducting properties. It comprises winding superconducting material into a plurality of inner coils and a plurality of outer coils, the inner and outer coils having a fixed shape; placing a tubular member between the inner and outer coils; placing the inner and outer coils with the tubular member therein within a collaring member to form a collared coil subassembly; securing the collared coil subassemblies between a pair of U-shaped yoke half assemblies and a pair of arcuate-shaped shell members to form a cold mass assembly; positioning the cold mass assembly in a vacuum vessel assembly having a cooling tube, through which is passed a cryogenic fluid, disposed therein, to thereby form a superconducting magnet; joining a plurality of the superconducting magnets into a ring-shaped structure, whereby a particle accelerator having superconducting properties is constructed
