Application of EPICS in accelerator control system

Accelerator control system is the core of the accelerator. Laboratory physics and industrial control system (Epics) is jointly developed by the United States Los Alamos National Laboratory (LANL) and Argonne Laboratory (ANL) control system integration tool, which is widely used in the accelerator control system. EPICS control system has the advantages of openness, practicality, and reliability. In this paper, we study the accelerator physics equipment send PV and applications of OPCUA variables under EPICS. With the application of PV and OPCUA variables in EPICS and the use of visual control development platform CSS, accelerator controllers can command the physical hardware of accelerator better in a software way.
