The control system design of the standing wave accelerator extension frequency automatic frequency

Objective: To design a standing wave accelerator extension frequency automatic frequency control system in order 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 frequency control system. Results: By eliminating the multiple values of anode voltage change, a standing wave accelerator extension frequency automatic 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 reliable work, obtaining good effect.
