Development of CSR High-Frequency Power Source Control System Based on Zynq SoC

The high-frequency system provides energy for the accelerator beam flow, and its working status directly determines the quality of the bundle stream [1] . In order to improve the stability and reliability of Lanzhou heavy ion accelerator cooling storage ring system, a power source control system based on Zynq SoC was developed. The system's hardware is based on the Xilinx company Zynq 7000 series FPGA as the core, with high-speed modulus transformation (ADC) and digital input output as the periphery. The software uses an EPICS architecture based on embedded Linux Power source control protection, cavity radio frequency voltage collection and analysis, high-frequency system failure analysis and automatic recovery, data archiving, remote human-machine interface and other functions. After testing, the control system indicators meet the needs of CSR and run stable and reliable. The control architecture and methods can be promoted to the control application of the solid power source system and other accelerators.
