Effect of Thermal Spread of Electrons on Stationary States of Vacuum Diode
Stationary states of electron beam with arbitrary velocity spread in a vacuum diode are studied. The velocity distribution function of beam electrons is assumed to be constant over a certain velocity range. The limiting current as a function of the velocity spread was obtained. It was ascertained that, within a certain range of parameters, stationary states with two types of virtual cathodes can exist.
