    Abstract: A multi-orientation cryostat 5 for a superconducting magnet 4 for use in a plurality of orientations. The cryostat 5 comprises a vessel 6 for holding cryogenic liquid and, leading away from the vessel, a quench duct 7 for allowing escape from the vessel of gas generated by boiling of the cryogenic liquid due to quenching of the magnet. The quench duct 7 is sinuous so as to provide at least to differently orientated anti-convection portions 71, each portion for functioning as an anti-convection portion with the cryostat in a respective corresponding orientation.

  • Patent number: 8950194
    Abstract: In order to minimize the loss of cryogen during transportation of superconductive magnet systems, or indeed at any time that the refrigerator is turned off, part of the boil-off gas is directed from the cryogen vessel through the refrigerator interface and past the refrigerator to cool the refrigerator. Some of the heat conducted along the refrigerator into the system is intercepted and removed by that part of the boil-off gas. The heat load onto the cryogenic vessel is thereby reduced, which in turn reduces the boil-off of cryogen from the cryogenic vessel. This part of the boil-off gas is then vented from the system along with the remainder of the boil-off gas, for example to leave the cryogenic liquid vessel via the access neck.

  • Publication number: 20150011395
    Abstract: A free liquid helium volatilization superconductive magnetic suspension device includes a low temperature container, a refrigeration, a cold screen, a liquid helium container, a superconductive rotor, a suspension coil, a rotor chamber, a liquid tube, a condenser and a pole-axis displacement sensor. The heat generated by the wires of the suspension coil can be prevented transferring to the liquid helium container by the room temperature current lead joint, the high temperature superconducting current lead joint and low temperature superconducting current lead joint. Therefore the volatilization of the liquid helium in the liquid helium container can be reduced. The status of free liquid helium volatilization in the liquid helium container can be reached through refrigeration cooling condenser to liquefy the helium. The device needs not to be input the liquid helium time after time and can run independently for a long term.

  • Publication number: 20150007587
    Abstract: A device for cooling a superconducting machine is disclosed, including a storage vessel which receives condensed coolant and from which the coolant can be fed via a pipe to the machine, wherein the storage vessel has a storage region and an evaporator region, which is separated from the former, with a heat source which continuously has a temperature above the boiling point of the coolant. The evaporator region is connected via a curved overflow pipe to the storage region in such a way that, when a defined coolant filling level is reached in the storage region, coolant flows via the overflow pipe automatically into the evaporator region and evaporates there.

  • Publication number: 20150007586
    Abstract: A method for converting a cryostat configuration (1) having a first container (2) with a liquid helium bath (3) and a second container (6) which is filled with liquid nitrogen (7) is characterized in that a cooling medium (12) which is in a gaseous state at a temperature of 60K and a pressure of 1 bar, is introduced into the second container and is cooled by a refrigerator (16) by means of a cooling circuit (11), the coolant lines of which are guided into the second container, to an operating temperature of ?60K. With this retrofit for existing cryostat configurations that utilize both liquid helium and also liquid nitrogen for cooling a superconducting coil, use of liquid nitrogen can be completely avoided and the evaporation rate of the liquid helium can also be considerably reduced without having to re-liquefy the cryogens used.

    Abstract: An arrangement for electrically conductively connecting two electrical units by means of a bipolar high voltage direct current transmission, in which between the units are arranged at least two electrical direct current cables constructed as superconductive cables. The superconductive cables are mounted separately from each other in a cryostat (1,2) suitable for conducting a cooling agent which has at least one metal pipe provided with a thermal insulation. The cryostats (1,2) are connected with at least one of their ends to a cooling plant (7) supplying the cooling agent and a pipeline (3) is placed parallel to the two cryostats (1,2). The pipeline (3) is connected at both its ends to the two cryostats (1,2) through valves (15,16,17) which are closed during uninterrupted operation and, in the case of an interruption at one of the superconductive cables, the pipeline (3) serves with the then open valves for conducting the cooling agent intended for the cryostat of the impaired cable.
