摘要： A cooling fluid coupling is disclosed for providing cooling fluid to a rotor having a super-conducting winding of a synchronous machine and a source of cryogenic cooling fluid. The fluid coupling comprises an inlet cooling tube and an outlet cooling tube in the rotor and coaxial with an axis of the rotor. The inlet cooling tube has an input port coupled to receive inlet cooling fluid from the source of cryogenic cooling fluid. The outlet cooling tube has an output port coupled to return cooling fluid from the rotor to source. A stationary motion gap seal separates the input port and output port of the coupling.

摘要： A magnet, such as an open magnetic-resonance-imaging (MRI) magnet) has a first assembly including a superconductive main coil and a magnetizable pole piece which, during magnet operation, has a temperature equal to generally the temperature of the main coil. In one example, a cryogenic-fluid (e.g., liquid helium) dewar encloses the main coil, and the dewar has an interior surface defined in part by a surface portion of the pole piece. A method for providing a homogeneous imaging volume for a magnet includes steps to construct the above-described magnet.

摘要： An open magnet useful in magnetic resonance imaging (MRI) applications. The magnet has two spaced-apart assemblies. Each assembly has a shielding coil located longitudinally outward from a main coil and a magnetizable pole piece spaced apart from and proximate the main and shielding coils. The method of the invention generates a magnetic field in a first area between the two assemblies while shielding a second area not between the two assemblies from a stray magnetic field by creating the previously-described open magnet.
