Abstract
Effect of negatively charged dust on resistive instability corresponding to the electrostatic wave is investigated in a Hall
thruster plasma when this purely azimuthal wave is tilted and strong axial component of wave vector is developed.
Analytical calculations are done to obtain the relevant dispersion equation, which is solved numerically to investigate the
growth rate of the instability. The magnitude of the growth rate in the plasma having dust particles is found to be much
smaller than the case of pure plasma. However, the instability grows faster for the increasing dust density and the higher
charge on the dust particles. The higher magnetic field is also found to support the instability.
