A simple model of a glow discharge electron beam for materials processing

Mostrar todas las versiones(2)

A simple semiempirical model of the electron beam generated by a pulsed cold cathode electron gun has been developed. The model describes analytically the observed self-focusing of the discharge and predicts the dynamical variation of the focal distance, in good agreement with experiments. This effe...
