Method and system for controlling a standing wave accelerator

It discloses a method and system for controlling a standing wave accelerator. The method comprising the steps of: generating an electron beam from the electron gun; injecting the electron beam acceleration tube; and controlling the microwave power source generates microwaves of different frequencies, the input of the accelerating tube, so that the accelerating tube at a predetermined frequency in different resonance switching between modes, generating an electron beam of appropriate energy. According to the above embodiment, in the process of modulation of the energy output simply by changing the frequency of the microwave power source, the accelerator without any change in the structure itself, simple method of operation. Further, the accelerating tube system simple structure without adding a special adjustment means.
