Abstract

This paper gives a theoretical treatment of the distribution of potentials within a Knudsen diode with surface ionization in the underneutralized regime in the presence of electron emission from the collector surface. A method is derived to calculate the potential distribution. It is shown that if the emission from the collector is sufficiently strong, spatially oscillatory (“wavelike”) potential distributions do not form; instead, a continuous transition occurs from a distribution with a virtual anode to one with a virtual cathode. Particular attention is focused on the neighborhood of the transition point from one of these distributions to the other.
