“…Here, let us note that there are few articles in which the experimental observation of the diocotron instability is reported, and there are a small fraction of articles dedicated to its theoretical and numerical study. Diocotron instability in a squeezed state situation was observed, but only in numerical simulations 16 .…”

Diocotron instability has been observed in the pure electron plasma formed in a split cathode coaxial diode. This plasma consists of electrons, trapped in the longitudinal potential well between the two parts of the cathode. The mathematical model of the electron squeezed state, which allows the calculation of the equilibrium plasma density, is presented. The model is applied in a comprehensive analysis of experimental data, and the presence of the diocotron instability is unambiguously confirmed.

In this article, the diocotron modes developing in a coaxial diode and the resonant magnetron modes forming in a six-vane A6 relativistic magnetron both fed by a split cathode are studied by Particle-in-Cell simulations. The split cathode is a novel type of cathode which sustains a column longitudinally oscillating electrons in a coaxial diode (smooth bore) or a magnetron over a non-emitting axial cathode conductor. The connection between the longitudinal oscillatory dynamics and the diocotron or magnetron mode development, as well as whether the diocotron modes affect the magnetron modes, is investigated.
