Low-injection energy continous linear electron accelerator

iiThis invention relates to continuous standing-wave linear electron accelerator comprising a low-energy electron source, for example, within a range of 10-20 keV, an accelerating structure ( or ′) for accelerating low initial energy electrons to required values; at least, one high-frequency power supply for the said accelerating structure ( or ′); a power supply for said electron source and high-frequency power supply; a receiving antenna, which is arranged in accelerating unit of accelerating structure ( or ′) and is used for emitting of high-frequency signal for controlling the amplitude and phase of accelerating field. Low-energy electron beam is directed to the first unit of accelerating structure ( or ′) contained successively accelerating units. The first of them is embodied in the form of a bunch resonator, the second unit is embodied in the form of a buster resonator, and successive units are used for increasing the electron energy. Also the following is proposed: selection of geometrical parameters of accelerating units, the versions of their arrangement in the said accelerating structure and the use of power supply modes by different high-frequency power sources such as magnetrons, externally excitable klystrons or klystrons operating in a self-oscillating mode with accelerating structure in a feedback circuit.
