Aim To design a set of automatic frequency control system of standing wave accelerator to achieve the purpose of eliminating the failure factors of automatic frequency control system. Methods By analyzing the working conditions of the microwave source and the accelerating tube, the frequency of the magnetron was adjusted by adjusting the frequency of the magnetron and a dose variable was added to start the general microwave phase-locked automatic frequency control system. As a result, the multi-value of the anode voltage was eliminated and an automatic frequency control system of standing wave accelerator was designed. Conclusion According to the theoretical analysis, the designed control system can work stably and reliably in a wide range of temperature and pulsation output pulsation by running on the test equipment, and achieved good results.
