SummaryThis paper will describe the aesign and operating experience with a high performance control system tailored to the requirements of the SupernlLAC accelerator. A large number (20) of the latest i6 -bit microcomputer boards are used in a paralleldistributed manner to get a high system bandwidth. Because of the high bandwidth, software costs and complexity are significantly reduced. The system by its very nature and design is easily upgraded and repaired. Dynamically assigned and labeled knobs, together with touch-panels, allow a flexible and efficient operator interface. An X-Y vector graphics system provides for display and labeling of real-time signals as well as general plotting functions. This control system allows attachment of a powerful auxiliary computer for scientific processing with access to accelerator parameters.
