摘要： A helium management control system for controlling the helium refrigerant supply from a common manifold supplies cryogenic refrigerators with an appropriate helium supply. The system employs sensors to monitor and regulate the overall refrigerant supply to deliver an appropriate refrigerant supply to each of the cryogenic refrigerators depending on the computed aggregate cooling demand of all of the cryogenic refrigerators. An appropriate supply of helium is distributed to each cryopump by sensing excess and sparse helium and redistributing refrigerant accordingly. If the total refrigeration supply exceeds the demand, or consumption, excess refrigerant is directed to cryogenic refrigerators which can utilize the excess helium to complete a current cooling function more quickly. If the total refrigeration demand exceeds the total refrigeration supply, the refrigerant supply to some or all of the cryogenic refrigerators will be reduced accordingly so that detrimental or slowing effects are minimized based upon the current cooling function.

摘要翻译： 用于控制来自普通歧管的氦制冷剂供应的氦管理控制系统为具有适当氦气供应的低温冰箱供应。 该系统采用传感器来监测和调节整个制冷剂供应，以根据所计算的所有低温冰箱的总体冷却需求向每个低温冰箱输送适当的制冷剂供应。 通过感应过多的稀疏氦和相应地重新分配制冷剂，向每个低温泵分配适当的氦气供应。 如果总制冷供应超过需求或消耗，则过剩制冷剂被引导到可以利用过量氦气来更快地完成当前冷却功能的低温冰箱。 如果总制冷需求超过总制冷供应，则对一些或所有低温冰箱的制冷剂供应将相应减少，从而基于当前的冷却功能使有害或减速效果最小化。

摘要： A heat exchanger within an insulated enclosure receives primary refrigerant at a high pressure and cools the primary refrigerant using a secondary refrigerant from a secondary refrigeration system. An expansion unit within the insulated enclosure receives the primary refrigerant at the high pressure from the heat exchanger and discharges the primary refrigerant at a low pressure. A supply line delivers the primary refrigerant at the low pressure to the load and a return line returns the primary refrigerant from the load to the primary refrigeration system. A system control unit controls operation of at least one of the primary refrigeration system and the secondary refrigeration system to provide a variable refrigeration capacity to the load based on at least one of: a pressure of the primary refrigerant delivered to the load, and at least one temperature of the load.

摘要： A refrigerator system or cryopump includes a first refrigerator having at least first and second stages, and a second refrigerator. A thermal coupling between the first stage of the first refrigerator and a cold end of the second refrigerator is restricted to maintain a temperature difference between the cold end of the second refrigerator and the first stage of the first refrigerator. The refrigerator system or cryopump also includes a radiation shield in thermal contact with the cold end of the second refrigerator, and a condensing surface, spaced from and surrounded by the radiation shield, and in thermal contact with a second stage, e.g., coldest stage, of the first refrigerator. The restricted thermal coupling can be configured to balance the cooling load on the two refrigerators.

摘要： A cryopump has a simple-to-manufacture frontal baffle plate with improved gas distribution and has a large-area second-stage array plate to capture Type II gases. The cryopump has a first-stage frontal baffle plate having orifices and flaps bent from and attached to the orifices. The cryopump has a second-stage top plate that is larger in area than cooling baffles of the second stage array.

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.
