Abstract

Plasma sheaths in front of six different material samples (BN, BNSiO2, Al2O3, SiO2, stainless steel, and silicon) used in various experiments and devices (Hall thrusters, plasma discharge, and microelectronics) are studied using the laser induced fluorescence diagnostic. The specific secondary electron emission (SEE) yield of each material is expected to induce differences in the sheath structure from one sample to another. The experiments are carried out in two different plasma discharges (multipolar device and ECR device), exhibiting distinct electron distribution functions: bi-Maxwellian and Maxwellian. The agreement between the two experiments is good and allows us to classify the materials in a consistent way regarding their SEE yields. The multipolar experiment results are compared to a 1D kinetic sheath model and a 1D-1 V kinetic sheath simulation code. The predictions of the model are discussed and are in good agreement with previous theory. The influence of the low energy impinging electrons on the SEE yield and emissive sheaths is investigated with the code.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • A polytropic electron model based on a single coefficient γ cannot capture correctly the kinetic physics of unmagnetized plasma plume expansions and introduces errors even in macroscopic quantities such as the electric potential and the ion density, especially in the plume peripheral and backflow regions.

    “It is therefore not surprising that a polytropic electron model based on a single coefficient γ cannot capture correctly the above physics and introduces errors even in macroscopic quantities such as the electric potential and the ion density, especially in the plume peripheral and backflow regions.”

  • Recent full PIC studies observed a clear anisotropy in the electron parallel and perpendicular temperatures of a planar plume expansion.

    “Recent full PIC studies 243-245 , also observed a clear anisotropy in the electron parallel and perpendicular temperatures of a planar plume expansion.”

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.
