Secondary-Electron-Emission Phase-Angle Distributions in High-Frequency Multipacting Discharges

Abstract
Numerical calculations of emission phase‐angle distributions of electrons in a low‐pressure, high‐frequency (multipacting) electric discharge have been carried out on a Burroughs 220 digital computer. An integral equation for the phase‐angle distribution is developed, and the numerical techniques used for its solution are outlined. The distribution of multipacting electrons with respect to the parameter v/v0, the ratio of impact velocity to emission velocity, has been calculated for several situations. These distributions show distinctive peaks which explain the success of the assumption v/v0=constant, used by previous workers, in predicting the breakdown region.
