Abstract

In this paper, we present the results of numerical modeling of transition to chaos in the relativistic BWO using 2D MAGIC particle-in-cell code. We compare the results with those of numerical and experimental studies. MAGIC allows simulating slow wave structures with realistic geometry and naturally takes into account such important phenomena as effects of transverse electron motion, frequency dependence of the end reflections and interaction with a non-synchronous forward wave reflected from the cutoff neck.
