In the last 30 years, numerical models have revealed different physical mechanisms
involved in the Hall thruster functioning leading to a bridge between analytical …

Numerical simulations of a magnetically shielded Hall effect thruster with a centrally
mounted cathode are performed with an axisymmetric hybrid particle-in-cell/fluid code and …

In wall-less Hall thrusters, the ionization of the propellant and the acceleration of the ions
occur outside the thruster [S. Mazouffre, S. Tsikata, and J. Vaudolon, in 50th …

Hybrid rocket propulsion can contribute to reduce launch costs by simplifying engine design
and operation. Hypergolic propellants, ie igniting spontaneously and immediately upon …

There is a growing need to consider alternative propellants for operation in Hall thrusters,
away from the conventional legacy of using xenon. This is particularly the case for small Hall …

Magnetically shielded miniature (MaSMi) is a low power (≤ 1 kW) long life (> 100 kg Xe
throughput) magnetically shielded Hall thruster that features an internally mounted hollow …

The applicability of a fully shielding magnetic field topology to a low-power xenon Hall
thruster was demonstrated through testing of the MaSMi-60. Although the discharge channel …

Magnetic focusing with xenon propellant has been verified in orbit from medium-to high-
power Hall thrusters but has yet to be achieved in low-power Hall thrusters. A magnetically …

The wall-less Hall thruster is expected to overcome the issue of wall erosion in miniaturized
Hall thrusters. A unique structure of negative gradient magnetic field is used to constrain the …

The external discharge plasma thruster removes the annular channel of the traditional Hall
thruster, allowing the ionization region to appear outside the thruster, which is expected to …
