Instability of two colliding plasma streams

Abstract

Instability of two colliding plasma streams with no magnetic field is investigated by means of toe graphical solution of the dispersion equation. Unstable regions of electron beam-electron coupling, electron beam-ion coupling or electron-ion beam coupling, and ion-ion beam coupling are determined as a function of wave number, beam velocity and phase velocity. The dependence of those regions on beam temperature and beam density is also shown.
