Abstract:
The Duke Free Electron Laser Laboratory currently op-erates
two FELs: the OK-4/Duke Storage Ring FEL, and the Mark III
IR FEL. Both of these systems were among the early adopters
of the Experimental Physics and Indus-trial Control System
(EPICS). The Mark III EPICS control system was completed and
operational in September, 1993. The Duke Storage Ring was
commissioned in November of 1994 using EPICS. These control
systems have proven to be very robust with high reliability
over the intervening years. An overview of these current
control systems and an upgrade strategy will be presented.
