PURPOSE:To simplify the electrode structure and to produce high brightness ion beam by employing a direct-heated filament in a cathode to accelerate in double stages while providing the ion accelerating function to the initial stage accelerating electrode thus eliminating the rear stage acceleration ...
Plasma electron gun for ribbon beam generation was designed on the basis of glow discharge with hollow cathode. Electrons were extracted through emission hole in the anode from plasma boundary, stabilized by metal mesh, and accelerated by the voltage applied between the anode and extractor. Electron...
