Effect of dust on tilted electrostatic resistive instability in a Hall thruster
Journal of Theoretical and Applied Physics, 2018 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.

Performance of a Cylindrical Hall-Effect Thruster Using Permanent Magnets [PDF]
, 2009 While annular Hall thrusters can operate at high efficiency at kW power levels, it is difficult to construct one that operates over a broad envelope from 1 kW down to 100 W while maintaining an efficiency of 45-55%. Scaling to low power while holding the

High Performance Power Module for Hall Effect Thrusters [PDF]
38th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2002 Previous efforts to develop power electronics for Hall thruster systems have targeted the 1 to 5 kW power range and an output voltage of approximately 300 V. New Hall thrusters are being developed for higher power, higher specific impulse, and multi-mode operation. These thrusters require up to 50 kW of power and a discharge voltage in excess of 600 V.
