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： A helium management control system for controlling the helium refrigerant supply from a common manifold supplies a plurality of cryogenic refrigerators with an appropriate helium supply. 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 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 refrigerant and redistributing refrigerant accordingly. If the total refrigeration supply exceeds the total refrigerant demand, or consumption, excess refrigerant is directed to cryogenic refrigerators which can utilize the excess helium to complete a current cooling function more quickly. Similarly, 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：用于控制来自公共歧管的氦制冷剂供应的氦管理控制系统为多个低温冰箱供应适当的氦气供应。该系统采用多个传感器来监视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。通过检测过量稀疏氦制冷剂并相应地重新分配制冷剂，将适当的氦气供应分配给每个低温泵。如果总制冷供应超过总制冷剂需求或消耗量，则过量的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。类似地，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地减小，从而基于当前的冷却功能来最小化有害或减速效果。

摘要： A piston includes a circumferential groove having a dynamic split seal ring having a flat axially facing surface, a static seal ring having a flat axially facing surface abutting the flat surface of the dynamic seal ring, and a spring mounted within the groove. The spring exerts an axial force on the static seal ring that serves to distribute the axial load with a static seal over the dynamic split seal, thereby preventing shuttling of the split seal within the groove and restricting the leak path of the seal. Preferably, the static seal ring is a polymer and can be an L-ring, a load ring with a flange that abuts the piston body, or flanged designs. In addition, a load ring can be fitted between the L-ring and the spring. The split seal ring has at least one radial spring mounted within the seal ring to create a radial force on the split seal ring. The piston can also include a sleeve that mounts to the piston body, the sleeve forming a wall of the groove. The piston can be a displacer mounted within a cylinder of a refrigerator.

摘要： In a fast partial regeneration process, the second stage of a cryopump is heated as purge gas is applied to the cryopump. In a test loop, the purge gas is turned off and the roughing valve is opened. If the cryopump is judged to be sufficiently empty of gases from the second stage by being roughed to a sufficiently low pressure in a short period of time the system proceeds to a reconditioning phase. If the system fails the test, however, it is repurged with a burst of warm purge gas and then retested. After passing the emptiness test, the pressure is further reduced by the roughing pump as heat is applied to the second stage. The heat is then turned off for cool down as the system continues to be rough pumped to a base pressure. At about the base pressure, the roughing valve is cycled to maintain the cryopump pressure at a level near to the base pressure. Where multiple cryopumps are coupled to a common roughing pump manifold, they are processed through a partial regeneration sequence in lock step to avoid cross contamination.
摘要翻译：在快速部分再生过程中，当吹扫气被施加到低温泵时，加热低温泵的第二阶段。在测试循环中，关闭吹扫气体，打开粗压阀。如果通过在短时间内将低温泵粗糙化到足够低的压力，则系统进入修复阶段，从而将低温泵判断为足够空的第二级的气体。然而，如果系统测试失败，则会用一阵温和的吹扫气体重新测试，然后重新测试。在通过空白试验之后，当加热到第二阶段时，由粗加工泵进一步降低压力。然后，随着系统继续粗略地泵送到基础压力，然后将热量关闭以冷却。在大约基本压力下，粗循环阀循环，以将低温泵压力保持在接近基本压力的水平。当多个低温泵连接到普通的粗加工泵歧管时，它们通过锁定步骤中的部分再生序列进行加工，以避免交叉污染。

摘要： A secondary pressure relief valve assembly is coupled to a cryopump relief valve for reducing the gas load on the cryopump. The pressure relief valve assembly comprises a main housing mounted to a crypoump exhaust conduit enclosing that portion of the cryopump valve typically exposed to the external environment. A second relief valve is mounted to the main housing and operates in series with the cryopump valve to exhaust pressurized gases from the cryopump during regeneration. A pump is coupled to a port on the main housing and maintains a pressure within the main housing which is less than the pressure of the external environment. As such, the pressure differential across the cyropump valve is reduced. Since the leakage and permeation gas loads are linearly related to the pressure differential, they are correspondingly reduced.

摘要： A cryopump is capable of pumping a process chamber at a process pressure and differentially pumping a second chamber such as an RGA independently at a substantially lower pressure. A member extends through the cryopump housing into a low pressure region disposed within the second stage array. The member comprises a port for accessing the low pressure region, thus providing an independent differential pumping source. No physical seal is required between the member and the main cryopump volume to maintain the pressure differential.

摘要： A recondenser with a primary heat exchanging surface for recondensing boil-off within a cryostat provides a second heat exchanging surface for removing heat leak into the cryostat. The second surface is cooled by the same working fluid that cools the primary surface, but at a temperature intermediate that of the primary surface and associated cooling apparatus which is remote from the cryostat. An intermediate transfer line transfers working fluid from an intermediate portion of the cooling apparatus to the second surface which is in heat exchange relation with a radiation shield of the cryostat but is out of physical contact with the radiation shield. The cooling apparatus includes a mechanical refrigerator which further cools working fluid returned from the second surface through the intermediate transfer line. The intermediate transfer line is preferably positioned in a non-contact helical manner about a final transfer line which carries the working fluid to the primary surface. The two transfer lines form an assembly which is less than about one inch in outer diameter and is removeably positioned in the cryostat. The intermediate transfer line is thermally isolated from the final transfer line within the assembly.

摘要： A cryopump 20 for differentially pumping water vapor and inert gases from a work space comprising a two stage refrigerator 45 in which a radiation shield 32 substantially encloses a second stage cryopanel 40. The radiation shield 32 incorporates a baffle plate 34 which condenses higher condensing temperature gases and restricts passage of low condensing temperature gases through orifices 36 to the second stage cryopanel 40. Backside pumping ports 38 provide a flow path to the second stage refrigerator for residual gases within the cryopump 20. This creates a high vacuum within the cryopump and allows it to operate at maximum efficiency.
