| Abstract: | A feed-forward automatic control system based on a novel control principle is developed, in order to compensate the amplitude and phase fluctuations of the microwave field in the thermionic RF gun cavity. The fluctuations, which are mainly caused by beam-loading effect, can be effectively restrained through this method. It is experimentally demonstrated that the novel control system has the excellent characteristics of stability and reliability. |
