Abstract
The Chinese Accelerator Facility for Super-heavy Elements (CAFe) was designed by the Linear Accelerator Center, Institute of Modern Physics, Chinese Academy of Sciences (IMP), and is currently in regular operation. As a national science facility, it plays a significant role in the development of accelerator technology in China. This paper presents a detailed description of a new beam automatic recovery control system that was proposed, designed, and implemented by our team for CAFe. The entire project, including hardware and software construction, was completed in January 2021. The hardware consists of a field-programmable gate array (FPGA) based master–slave control board, while the software implementation was carried out using a combination of Python and Experimental Physics and Industrial Control System (EPICS). The system can effectively and reliably perform required actions based on different beam situations, and also enables automatic machine protection.
