Mirrored Winding Pack Concept for Spiral-Grooved, Stacked-Plate, Non-Insulated Superconducting Magnets

Magnets and magnet systems include stacked magnet baseplates. Each of the plates includes grooves that contain windings of a conductor (e.g. a high temperature superconductor) that generates a magnetic field when current is passed through. This field generates Lorentz forces in the stack that press the conductors in different directions and with different magnitudes. Thus, the plates are oppositely oriented (mirrored) so that these forces always press the conductors into the grooves, rather than pulling them out of the grooves. The conductors may be further reinforced in their grooves with solder or epoxy potting. Some stacks may have more plates in one orientation than in the mirrored orientation, because the Lorentz forces need not be symmetrical with respect to a midpoint of the stack, e.g. when the system experiences externally-applied magnetic fields. Additional, mirrored side plates may be added in some configurations.
