Kinetic instability of the ion acoustic mode in permeating plasma of electron–positron and ion

Abstract

Kinetic instability of the ion acoustic mode is observed in permeating plasma of electron, positron, and ion in a similar background plasma system. The linear growth of the wave is excited only when the streaming speed of the flowing plasma reaches a critical speed for all temperature ratios. Presence of positron, however, only shows a quantitative modification in the critical speed of the flowing plasma.
