The Duke storage ring control system
The Duke storage ring is a dedicated facility for the UV-VUV FEL operation. The low level computer control system for the Duke storage ring is developed using EPICS. The control hardware employs several different architectures including CAMAC, GPIB, Allen Bradley, and VME. The high level control is implemented in Tcl-Tk scripts running on SPARCstations. Tcl-Tk provides the global control capabilities such as the energy ramping, the orbit compensation, and the tune and chromaticity control. The Duke storage ring control system was tested and operational for storage ring commissioning in Nov. 1994. During commissioning, additional control tools were developed to facilitate the operation.
