Oscillatory solutions for a diode with counter-streaming electron and ion beams

Abstract

Abstract A plasma diode with counter-streaming electron and ion beams has as a rule more than one time-independent solution. Stability features of the steady state solution with ion reflection from a potential barrier are studied numerically. It was found that there is a threshold in the diode length beyond which nonlinear oscillations occur as an alternative instead of such solutions. Features of the oscillations are studied.
