The Impact of Harness Impedance on Hall Thruster Discharge Oscillations [PDF]
Hall thrusters exhibit characteristic discharge voltage and current oscillations during steady-state operation. The lower frequency breathing-mode current oscillations are inherent to each thruster and could impact thruster operation and power processing

CHARACTERIZATION OF KRYPTON PERFORMANCE IN A LABORATORY 300 W MAGNETICALLY SHIELDED HALL-EFFECT THRUSTER [PDF]
Xenon has long been the propellant of choice in Hall Thrusters; however, significant work has been performed to produce thrusters capable of utilizing alternate propellants due to xenon’s price and scarcity.

Hall-effect thruster-cathode coupling : the effect of cathode position and magnetic field topology [PDF]
, 2009 Hall-effect thruster (HET) cathodes are responsible for the generation of the free electrons necessary to initiate and sustain the main plasma discharge and to neutralize the ion beam. The position of the cathode relative to the thruster strongly affects
