Abstract: A superconducting generator including an armature configured to be rotated via a shaft and a stationary field disposed concentric to and radially outward from the armature. The stationary field including a superconducting field winding and a vacuum vessel having an inner wall of one of a non-magnetic material or a paramagnetic material facing the armature, an opposed outer wall of a ferromagnetic material and a plurality of sidewalls coupling the inner wall and the opposed outer wall. The superconducting field winding is disposed in the vacuum vessel. A wind turbine and method are additionally disclosed. The wind turbine includes a rotor having a plurality of blades. The wind turbine further includes a shaft coupled to the rotor. Moreover, the wind turbine includes the superconducting generator coupled to the rotor via the shaft.

Abstract: A magnetic resonance imaging device is described that includes multiple magnetic coils to generate a magnetic field. Additionally, the magnetic resonance imaging device may include one or more radial gaps within some or all of the magnetic coils (e.g., primary magnetic coils, bucking coils, and so forth) in which radial spacers may be located to help preserve the homogeneity of the magnetic isocenter of the primary magnetic coils during operation.

Abstract: Embodiments of the invention are utilized to improve shimming capability while reducing radial space and the volume required to contain active shim coils by nesting the coils of different degrees and orders inside each other and limiting the azimuthal span of the individual saddle coils. This allows two or more radial shim sets to be combined together in the same layer resulting in a significant radial savings that increases the useable portion of an MRI system.
