Studies have mostly focused on the magnetic field distribution within the channel and near …

The role of the electrically conductive vacuum chamber wall in the completion of the
discharge circuit of a Hall effect thruster is experimentally investigated. The Aerojet …

With the development of electric space propulsion and all-electric propulsion technologies,
the application range of the Hall effect thruster (HET) has gradually expanded. As an …

Effects of the propellant, propellant mass-flow rate, and discharge voltage on the
characteristics of the plume of small Hall thrusters are studied using a particle-in-cell Monte …

In this work, a krypton Hall thruster is used to study the influence of low-frequency oscillation
on the focusing characteristics of the plasma beam. The experiment results show that the …

It has been recognized that the application of magnetic shielding technology deteriorates the
plume divergence efficiency of a Hall thruster. To try to alleviate this effect, three magnetic …

In this study, we investigated the effects of the magnetic field profile near a ring anode on the
