Studies of growing waves in Hall thruster beam plasma under the influence of electron temperature
Abstract
In this paper, the effect of electron temperature on the resistive instability has been investigated in a Hall thruster beam plasma. The dispersion relation for the axial-azimuthal propagating waves and the instabilities has been derived using the first-order perturbation technique under the effects of various parameters. The growth rate shows Gaussian-type behaviour with the magnetic field, azimuthal wavenumber and the electron temperature but it increases linearly with axial wavenumber, beam density, beam velocity and collisional frequency. The growth rate decreases with the drift velocity of electrons. The real frequency almost increases with the axial-azimuthal wavenumbers, electron drift velocity, electron temperature and the collisional frequency.
