Controlling a digital twin of the CEBAF injector from EPICS

The Experimental and Instrumental Control System EPICS is used to control magnets and to read data from diagnostic devices in the CEBAF accelerator. We describe a prototype system where an EPICS installation, local on a laptop or Raspberry Pi, controls beam optics simulations. They can be running on the same computer or on a separate computer connected via the network. The prototype focuses on modeling and controlling the moderately complex injector beam line of CEBAF, which only comprises a few dozen magnets and beam monitors.
