Effect of anode dielectric coating on Hall thruster operation [PDF]
Applied Physics Letters, 2004 An interesting phenomenon observed in the near-anode region of a Hall thruster is that the anode fall changes from positive to negative upon removal of the dielectric coating, which is produced on the anode surface during the normal course of Hall thruster operation. The effect of the anode coating on the anode fall is studied experimentally using both

Thermal stability of the krypton Hall effect thruster [PDF]
Nukleonika, 2017 Abstract The Krypton Large IMpulse Thruster (KLIMT) ESA/PECS project, which has been implemented in the Institute of Plasma Physics and Laser Microfusion (IPPLM) and now is approaching its final phase, was aimed at incremental development of a ~500 W class Hall effect thruster (HET). Xenon, predominantly used as a propellant in the state-

The water electrolysis Hall effect Thruster [PDF]
, 2022 This study proposes operating a Hall effect Thruster (HET) on the products of in-situ water electrolysis. Oxygen is supplied to the anode and hydrogen to the cathode to mitigating poisoning. In comparison to other alternative HET propellants water is non-toxic, low cost, highly storable, and allows synergies with chemical propulsion systems.

Numerical Modeling of Erosion in Hall Effect Thrusters
ParticlesThe erosion of the accelerating chamber walls is one of the main factors limiting the operational life of Hall effect thrusters (HETs), and it is mainly related to the sputtering of ceramic walls due to the impacting energetic ion particles. The erosion phenomenon is investigated by means of a numerical model that couples the plasma model HYPICFLU2 ...
