Simulation study on electron extraction mechanism of an ECR neutralizer
Abstract
Abstract To investigate electron extraction through the orifice of an electron cyclotron resonance (ECR) neutralizer, two-dimensional axisymmetric particle-in-cell simulations with a Monte Carlo collision algorithm (PIC-MCC) have been conducted. The diagnostic experiment of Langmuir probe verified that the plasma distribution in the ECR neutralizer with an L-shaped antenna was circumferentially uniform, which provided the experimental basis for two-dimensional axisymmetric simulations. The distribution of plasma parameters and extracted electron current of the neutralizer were obtained by tracking the motion of electrons and singly charged xenon ions, simulating the elasticity, excitation, ionization and Coulomb collisions. Moreover, computational results and analysis demonstrated that there were two kinds of electronic extraction channel in the ECR neutralizer. One was affected by the potential well between magnetic well and anode, another was affected by the valley potential of electronic double sheath. The property of these two electronic extraction channels determined the variation of extracted electron current and mode conversion voltage.

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.
