    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。
