Kinetic plasma dynamics in a radial model of a Hall thruster with a curved magnetic field

Open access

Abstract

A 1D particle-in-cell model of a Hall thruster discharge is used to analyze the effect of a curved magnetic topology in the radial plasma response and the plasma fluxes to dielectric walls. The kinetic solution shows a significant replenishment of the velocity distribution function tail and temperature isotropization for both negative (i.e. anode pointing) and positive curvatures. The new radial magnetic force is electron confining or expanding for, respectively, negative and positive curvatures, and this modifies significantly the electric and pressure radial forces. As a consequence, the plasma density near the wall and the degree of radial ion defocusing are affected: they are highly reduced for negative curvatures, the case of higher interest. For positive curvatures, the kinetic solution shows that the radial ion flow becomes supersonic within the plasma bulk, away from the Debye sheaths. An ancillary quasineutral fluid model is presented to explain this feature and other aspects of the kinetic solution. Some kinetic studies on additional phenomena complete the work.

  • Hybrid models represent the best compromise in terms of accuracy and computational cost for modeling plasma thruster plume expansion and its interaction with the spacecraft.

    “Hybrid models 225-234 have therefore emerged in this context, as they represent the best compromise in terms of accuracy and computational cost for modeling the plasma thruster plume expansion and its interaction with the spacecraft.”

  • Hybrid models feature a kinetic treatment of the ion species (and in some cases of the neutrals as well) so that CEX collisions are correctly captured, and a fluid modeling of the fastest species, the electrons.

    “In fact, they feature a kinetic treatment of the ion species (and in some cases of the neutrals as well) so that CEX collisions are correctly captured, and a fluid modeling of the fastest species, the electrons, which are subject to conservation equations.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
