Markley, D.

The DZERO VLPC Cryostat and the Superconducting Solenoid both require an insulating Vacuum of 10{sup -5} Torr or less. There is a vacuum system on the Detector Platform consisting of 2 Turbomolecular vacuum pumps and their associated piping, valves, instrumentation that are dedicated to this task. This vacuum equipment requires an operator interface and control logic in order to function properly. The operator interface allows an operator to monitor, control and configure the proper pumping setup required at any given time. The control logic is needed to protect the Vacumm vessels and Vacuum equipment from catastrophic events that may harm them. This is typically done with interlock chains or strings.
