A distributed VME control system for the LISA superconducting linac

The control and diagnostic system for LISA, a new accelerator under construction, is presented. The system is based on a multiprocessor environment and uses interactive graphical workstations and the VME data acquisition standard. Particular care has been given to the operator-machine interface. A strict hierarchical structure has been designed into the system for reliability and flexibility. The discussion focuses on the structure of the control system, the hardware architecture, and the software environment.<
