    摘要： A magnet assembly for a Magnetic Resonance Imaging (MRI) system includes a vacuum vessel including an inner cylinder, an outer cylinder and a pair of tapered flanges connecting the inner and outer cylinders. The inner cylinder is made of a composite material. The outer cylinder and flanges are composed of several magnetic segments that provide a magnetic flux return path with low eddy currents. The segments are bonded together and electrically insulated from each other. A container, a thermal shield and a superconducting magnet coil assembly are disposed within the vacuum vessel. The superconducting magnet coil assembly includes a non-conductive cylindrical structure and superconducting coils. A thermally conductive cable is wrapped around the cylindrical structure and coils to form a thermally conductive envelope.

    摘要： A method for cooling a superconducting magnet enclosed in a cryostat includes introducing a gas into a cooling path in the cryostat from an input portion into a cooling path cooled by a refrigerator outside the cryostat. A heat exchanger inside the cryostat above the magnet cools the gas. The cooled gas flows through a magnet cooling tube contacting the magnet. The cooled gas removes heat from the magnet, and to the heat exchanger to re-cool and return to the superconducting magnet, thereby cooling and/or maintaining the magnet at a superconducting temperature.

    摘要： A superconducting magnet is described and includes at least one superconducting coil, at least one support member coupled to the superconducting coil and at least one compliant interface between the superconducting coil and the support member. The superconducting coil defines a radial direction. The superconducting coil supports the superconducting coil along an axial direction that is substantially perpendicular to the radial direction. The compliant interface is configured to move along the radial direction when the superconducting magnet is energized.

    摘要： A structure for superconducting magnets is provided. The structure includes a thermally conductive electrically resistive composite bobbin, a superconducting coil disposed around the thermally conductive electrically resistive composite bobbin for conducting current in a superconductive state. The structure also includes an electrically open cryogenic coil disposed on the thermally conductive composite electrically resistive bobbin, which can receive a flow of cryogenic fluid to maintain the superconducting coil in the superconductive state by transfer of heat from the superconducting coil to the electrically open cryogenic coil through the thermally conductive electrically resistive composite bobbin.
