Abstract:
1. A superconducting magnet assembly, comprising: a superconducting magnet configured to generate a static magnetic field; an iron shield configured to shield the superconducting magnet; a magnetic gradient coil assembly configured to generate a gradient magnetic field; and one or more magnetic lamination elements disposed on the iron shield to reduce eddy currents induced by the gradient magnetic field in the iron shield, wherein the one or more magnetic lamination elements are disposed on an interior surface of the iron shield in a configuration of one or more layers, at least one of the one or more layers comprising more than one magnetic lamination element, wherein one or more non-magnetic gaps are defined between adjacent magnetic lamination elements in the at least one layer, wherein the more than one magnetic lamination element in the at least one layer is disposed on the iron shield along a direction of the static magnetic field generated by the superconducting magnet, and wherein the one or more non-magnetic gaps are defined along the direction of the static magnetic field.
