Steady-states of relativistic Pierce diode in a regime with electron reflection from a potential barrier

Abstract

Abstract In this work we present the study of steady states of a relativistic Pierce diode. We take into account electron scattering by heavy background ions as well as electron reflection from a potential barrier. Using Lagrangian variables we solve the problem numerically. Steady-state solutions are visualized through the ‘Bursian’ and ‘Non-Bursian’ branches in a parametric plane. Features of these branches with varying in mean collision frequency are analysed.
