摘要： A vacuum network control system includes a plurality of nodes configured for control over operational processes of the system. The plural nodes are configured, in a network ring or other topology, as a selectable master node for controlling the operational processes. Control can be distributed among, and passed between, each of the nodes. Each node on the network monitors adjacent network connectors to detect a fault in the network. In response to a detected fault, a disconnect is mapped to the fault, and the network topology is reconfigured for continued communication among the nodes and with external devices.

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 portable display unit includes a serial port to connect to a device such as a vacuum network controller, cryopump, turbomolecular pump, gauges or compressor. In particular, the display unit can be plugged and unplugged to devices of different types. The portable display unit includes a display and control keys for programming, controlling and monitoring the functions of a device. The device accessible to the display unit includes a display interface having software code and files to interface with the display unit. Accordingly, the portable display unit can be used with any device having software code to interface with the display unit. The software code generates, refreshes and communicates menus to the portable display unit to provide graphical interface of the device's functions. The portable display unit further includes inner and outer hand grips so that the display unit can be held by hands of different sizes. The hand grips allow user with different hand sizes to firmly hold and navigate the display using control keys with fingers.

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.
