摘要： A high temperature superconducting (HTS) magnet coil disposed within a cryostat is configured with a thermo-siphon cooling system containing a liquid cryogen. The cooling system is configured to indirectly conduction cool the HTS magnet coil by nucleate boiling of the liquid cryogen that is circulated by the thermo-siphon in a cooling tube attached to a heat exchanger bonded to the outside surface of the HTS magnet coil. A supply dewar is configured with a re-condenser cryocooler coldhead to recondense boiloff vapors generated during the nucleate boiling process.

摘要： A method of storing biological samples in which the biological samples are stored in a stack within a vessel interior of an insulated vessel. A pool of liquid cryogen is maintained within the vessel interior by condensing cryogenic vapor boiled off of the pool of liquid cryogen with a cryocooler having a cold finger. The cryocooler and cold finger are positioned so that a cold heat exchanger of the cold finger is in thermal contact with the cryogenic vapor and is positioned above the stack, so as to also maintain a temperature difference within the insulated vessel, between a bottom region of the stack and a top region of the stack, of no greater than about 65K.

摘要： A refrigerated container and method capable of maintaining super frozen temperatures of about −50 degrees C. or less, includes container walls insulated to a value of at least about r-20, a cargo compartment configured for receiving cargo, and at least one refrigerant compartment configured for receiving refrigerant in the form of CO2 snow. The refrigerant compartment maintains the CO2 snow and vapor sublimating therefrom separately from the cargo compartment. The refrigerant compartment is located within the cargo compartment and configured to permit ambient atmosphere within the cargo compartment to contact at least three sides, and up to six sides, of the refrigerant compartment. The placement of the refrigerant compartment is also configured to generate a temperature gradient within the cargo compartment capable of generating convection therein, so that the super frozen temperatures are maintained within the cargo compartment without the use of external power sources.

摘要： A multi-bath apparatus and method for cooling a superconductor includes both a cooling bath comprising a first cryogen and a shield bath comprising a second cryogen. The cooling bath surrounds the superconductor, and the shield bath surrounds the cooling bath. The cooling bath is maintained at a first pressure and subcooled, while the shield bath is maintained at a second pressure and saturated. The cooling bath and the shield bath are in a thermal relationship with one another, and the first pressure is greater the second pressure. Preferably, the cryogens are liquid nitrogen, and the superconductor is a high temperature superconductor, such as a current limiter. Following a thermal disruption to the superconductor, the first pressure is restored to the cooling bath and the second pressure is restored to the shield bath in order to restore the superconductor to a superconductive state.

摘要： A cryogenic storage container is provided with a storage container, a vacuum container containing the storage container, and a heat shield. The cryogenic storage container is coupled to a cooling source equipped with a cryogenic freezer via transport piping so that the vibration of the cryogenic freezer cannot be directly delivered to the cryogenic storage container. The vibration can be further reduced by providing a bellows unit for transport piping.

摘要： A method and mechanism for eliminating one of the magnetic circuits in a conventional two motor Stirling cryocooler. The inventive cooler is a Stirling cycle cryogenic cooler with a magnetic circuit for generating a field of magnetic flux in two separate magnetic gaps; a first coil disposed in the flux field of one gap; and a second coil disposed in the flux field of the second gap. The second coil is mounted for independent movement relative to the first coil. In a specific embodiment, the first coil is a compressor coil and the second coil is a displacer coil. The coils are energized with first and second variable sources of electrical energy in response to signals from a controller.
