    摘要： A cryogenic refrigerator has a refrigeration cylinder and at least two displacers. Each displacer reciprocates in the refrigeration cylinder and moves refrigeration gas through the refrigeration cylinder. A regenerator cools the refrigeration gas, and gas control valves admit high pressure gas into the refrigeration cylinder and exhaust gas from the refrigeration cylinder. The refrigerator also has linear motors operatively connected to displacers, and the linear motors drive the displacers in reciprocating movement. A position sensor is provided to determine a parameter of the displacers during reciprocation. A controller is operatively connected to the linear motors to control the linear motors. The controller controls a parameter of the two displacers during reciprocation. The parameter can be stroke length, stroke speed, stroke phase or another parameter of the displacer for temperature control of the cryogenic refrigerator. The cryogenic refrigerator may also include a device to remove vibration.

    摘要： A refrigerant management system controls the supply of refrigerant from two or more variable speed and fixed speed compressors to a plurality of cryogenic refrigerators. The system employs a plurality of sensors to monitor and regulate the overall refrigerant supply to deliver an appropriate refrigerant supply to each of the cryogenic refrigerators. The amount of refrigerant to supply is based on an aggregate demand for refrigerant from the plurality of cryogenic refrigerators and a refrigerant correction metric. An appropriate supply of refrigerant is distributed to each cryogenic refrigerator by adjusting the speed of the variable speed compressors or, alternatively, selectively turning the compressors on or off. The speed of the variable speed compressors is adjusted by determining an amount of refrigerant to supply to the plurality of cryogenic refrigerators. If the aggregate demand for refrigerant exceeds the capacity of the compressors, then the speed of a refrigerator within the plurality of refrigerators is adjusted.

    摘要： In a cryogenic refrigerator, a displacer 12 and its drive piston 28 are guided by a displacer guide 32 seated within an expander body 16. An expander cap 40 enclosing a spring volume 38 extends within the expander body 16 and abuts the displacer guide 32. An indium seal 50 is positioned in the chamfer at the intersection of the cap, body and guide.

    摘要： Cryopump components are improved using thin layer heating elements for temperature control or to serve as heaters. These heating elements may be located and prevent pooling during regeneration. The temperature control may also be achieved through the use of ceramic heating elements. The ceramic heating elements may also include a second function of structural support within the cryopump. Temperature control may further be achieved via the radiation shield, where the radiation shield includes a clad sheeting or coating.

    摘要： A cryogenic refrigerator includes a shell having a reciprocative displacer and an adsorbent mounted within the shell. In one embodiment, the displacer contains both a regenerative media and the adsorbent, with the regenerative media placed between the adsorbent and a cold end of the displacer. In a method for removing contaminants from the reciprocative displacer, compressed and expanded helium gas is displaced through the displacer, with the adsorbent positioned to adsorb contaminant gases entrained in the helium gas. In another method, a filtering refrigerator containing an adsorbent is coupled to a helium circuit of a refrigeration system to remove contaminants from the circuit.
