摘要： A combination refrigerator and current lead assembly includes a pulse tube having a cold end and a warm end. A first electrical connector is attached to the warm end. A second electrical connector attached to the pulse tube supplies current to a lead, for example, a high temperature superconductor lead. The assembly includes a second pulse tube having an electrical connector attached at its warm end and a second electrical connector for supplying current to a lead. The second electrical connectors are attached to the cold ends of the pulse tube. The pulse tubes are formed from an electrically conductive material. An electrical isolator electrically isolates the pulse tubes from each other. Additional electrical isolators electrically isolate the pulse tubes from a compressor, valve, and regenerators of the system.

摘要： A cooling system is configured to control the flow of a refrigerant by controlling the rate at which the refrigerant is heated, thereby providing an efficient and reliable approach to cooling a load (e.g., magnets, rotors). The cooling system includes a conduit circuit connected to the load and within which a refrigerant circulates; a heat exchanger, connected within the conduit circuit and disposed remotely from the load; a first and a second reservoir, each connected within the conduit, each holding at least a portion of the refrigerant; a heater configured to independently heat the first and second reservoirs. In a first mode, the heater heats the first reservoir, thereby causing the refrigerant to flow from the first reservoir through the load and heat exchanger, via the conduit circuit and into the second reservoir. In a second mode, the heater heats the second reservoir to cause the refrigerant to flow from the second reservoir through the load and heat exchanger via the conduit circuit and into the first reservoir.

摘要： A cryogenic cooling system is configured to control the flow of a heat transfer fluid through a remote thermal load, such as a superconducting magnet or rotor. The cryogenic cooling system includes a refrigerator including a cryogenically cooled surface and a cryogenic fluid transport device disposed for circulating a heat transfer fluid between the cryogenically cooled surface and the remote thermal load. The cryogenic fluid transport device advantageously serves as device for providing the necessary mechanical force necessary to move the heat transfer fluid from the cryogenically cooled surface (e.g., end of a cryocooler) to the remote thermal load. Thus, unlike conventional cooling arrangements the heat transfer fluid does not require a phase change.

摘要： A system for cooling a superconductor device includes a cryocooler located in a stationary reference frame and a closed circulation system external to the cryocooler. The closed circulation system interfaces the stationary reference frame with a rotating reference frame in which the superconductor device is located. A method of cooling a superconductor device includes locating a cryocooler in a stationary reference frame, and transferring heat from a superconductor device located in a rotating reference frame to the cryocooler through a closed circulation system external to the cryocooler.

摘要： A cryogenic refrigerator for cooling a rotating device includes a stationary regenerator, and a rotatable cold heat exchanger coupled to the stationary regenerator to rotate relative thereto. The cryogenic refrigerator is, for example, of the Gifford-McMahon type or pulse tube type. In the Gifford-McMahon type, a stationary cylinder houses the regenerator, and a rotatable cylinder mounted to the cold heat exchanger is concentrically arranged about the stationary cylinder. Alternatively, the rotatable cylinder is axially offset of the stationary cylinder. A seal, for example, a ferrofluidic seal, is located between the stationary and rotatable cylinders. In the pulse-tube type, a pulse tube is concentrically arranged about the regenerator, and the cold heat exchanger includes a stationary portion coupled to the regenerator and a rotatable portion coupled to the pulse tube. A back-up valve system is provided for increased reliability.

摘要： A high temperature superconductor lead assembly for reducing the heat leak into a cryocooled system features a shroud configured for at least partial submersion in a cryogenic fluid contained within a bath chamber, and a high temperature superconductor lead element at least partially contained within the shroud. In use, a portion of the high temperature superconductor lead element contained within the shroud extends below a fluid level of the cryogenic fluid in the bath chamber. The portion of the high temperature superconductor lead element is thermally shielded by the shroud such that it is maintained at a temperature higher than the temperature of the cryogenic fluid. The shroud is a double-walled vacuum structure with a sealed end and an open end. In use, the open end is submerged in the cryogenic fluid.
