Development of Operator and User Requested Control System Applications;
Experience with the SLC Control System at SLAC

M. Stanek

The evolution of the SLC Control System at SLAC has included the development of many applications and user interface features generated from accelerator operator and accelerator physicist requests. These applications are written and maintained by the Controls Software Engineering group. The process of developing and supporting user requested control systems applications at SLAC is discussed, including the effects of organizational structrue, formal and informal procedures, and general responsibilities. Effects of control system architecture on fulfilling user application requests is also discussed.
