Objective To design a standing wave accelerator extension frequency automatic frequency control system in or- der to achieve the purpose of removing automatic frequency control system failure factors. Methods Through the automatic frequency control system to coordinate the microwave source and accelerating tube working status analysis, adjust the frequency of magnetron, add a dose of variables and to start the general microwave phase - locked automatic fYequency control system. Results By eliminating the multiple values of anode voltage change, a standing wave accelerator extension frequency automat- ic frequency control system was designed. Conclusion In accordance with the theory analysis, the desiged control system by running on the test equipment can in a large range of temperature and pulse which modulation output pulse is stable and relia- ble work, obtaining good effect.
