Intense Annular Relativistic Electron Beam Generation in Foilless Diodes

Abstract

The generation of intense annular electron beams in cylindrical foilless diodes is analyzed. A beam equilibrium model is used to determine the diode current. At low voltage the current is very nearly that of the space charge limited beam. However, at higher voltages the current can be substantially less than the space charge limit. The analysis is compared to detailed particle in cell simulations.
