Density gradient driven instability in an plasma system having temperature gradients

Abstract

A theoretical model is developed to investigate the density gradient driven instability in an [Formula: see text] plasma system with the consideration of finite temperature of both the electrons and the ions where these species are magnetized. The dependence of temperature of the electrons and ions, charge of the ions, plasma background density, and strength of magnetic field on the variation of normalized growth rate has been investigated and portrayed for different channel lengths. The ion temperature gradient that generally exists in the considered plasma systems is also included to investigate its impact on the growth rate of the instability.
