AET has successfully developed various microwave/RF electron guns in the past. They are high gradient RF guns with a thermionic cathode, a triode type microwave electron gun and a micro-miniature microwave/RF electron gun using a coaxial resonator. The triode type microwave electron gun is an epoch-making product which is able to simultaneously eliminate the back bombardment phenomenon, reduce emittance of the electron beam and enables excellent control of the pulse width. While the novel micro-miniature microwave/RF electron gun with a diameter of only 5mm can be used as a electron or X-ray source for industrial and medical applications.
