    摘要： A compressive strut for cryogenic applications includes a tube with a cylindrical bore wall defining an internal cavity, a rod of filling material within the cavity which has low thermal conductivity, and structure in engagement with the rod, such as end plugs partially inserted into the ends of the tube and in contact with the rod. The tube may be formed of a composite material such as fiberglass within a matrix of epoxy, wherein the fiberglass fibers are wound circumferentially. The plug at one end of the strut is attached to the warm support structure and the plug at the other end is attached to the cold structure, such as a superconducting magnet which is maintained at cryogenic temperatures. Compressive pressure applied by the magnet to the strut causes the plugs to press inwardly on the filling material rod, expanding the rod radially. The circumferentially strong tube resists outward expansion of the rod and carries a significant portion of the compressive pressure applied to the rod so that the rod itself does not have to support the compressive forces applied to it. Consequently, the rod can be formed of a relatively low thermal conductivity material which need not have high strength, and the tube need only have high strength in the circumferential direction.

    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 cold mass for a superconducting magnet system in one example comprises a superconducting magnet, a cryogenic cooling circuit, and a magnet and cooling circuit support. The magnet and cooling circuit support comprises a substantially conductive coupler that serves to couple the superconducting magnet and the cryogenic cooling circuit. The cryogenic cooling circuit comprises an inlet path and a substantially upward outlet path. The inlet path avoids direct conductive thermal engagement with the substantially conductive coupler. The substantially upward outlet path comprises direct conductive thermal engagement with the substantially conductive coupler.
