Particle-in-cell simulations of Hall thruster acceleration and near plume regions
Abstract
The results of 1-D azimuthal, and 2-D z-θ, particle-in-cell simulations of Hall thruster acceleration and near plume regions are reported. The 1-D simulations show that fast moving electron waves drive coherent, large amplitude, ion acoustic waves. The ion waves become azimuthally coherent too quickly for ion sound to be the cause; the coherence comes from early electron waves. 2-D simulations with only fast moving, main beam, ions result in ion acoustic wave amplitudes much lower than those in the 1-D calculations. The addition of a small amount of ionization in the domain, at a rate consistent with Hall thruster parameters, causes the potential profile to divide into two distinct regions. In the upstream portion of the domain, the potential profile is very steep; in the downstream portion, the potential profile is almost flat. Electron transport in the two regions is discussed.

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.
