20.500.12556/RUL-156125 Analysis of ion orbits in front of a negative planar electrode immersed in an oblique magnetic field The orbital motion approach is used to analyze the ion impact on a negatively biased planar wall immersed in a strongly magnetized plasma. It is assumed that the given homogeneous magnetic field forms a small angle with a planar negatively biased electrode, while the inhomogeneous electric field is perpendicular to the electrode. Spatial dependence of the electric field is modeled in such a way that the electric field exhibits two-scale behavior, which is characteristic of plasma sheath problems. The equation of motion of a singly charged deuterium ion is solved for a large variety of parameters and initial conditions. The effects of electrode bias, magnetic flux density, magnetic field angle, initial velocity, electric field scaling, and electrode bias are investigated. It is found that the impact angles of ions are distributed over a surprisingly wide range, and in a vast majority of cases, the angle of impact is several times larger than the magnetic field angle. The study is relevant for the analysis of ion flow to the electrodes in fusion plasmas, i.e., divertors of tokamaks. plasma divertor fusion Larmor radius magnetic field plazma divertor fuzija Larmorjev radij magnetno polje true false true Angleški jezik Slovenski jezik Članek v reviji 2024-05-09 13:16:08 2024-05-09 13:16:11 2024-05-10 03:45:55 0000-00-00 00:00:00 2022 0 0 18. str. iss. 12, [article no.] 125211 Vol. 12 Dec. 2022 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 533 2158-3226 10.1063/5.0131511 132962051 125211_1_online.pdf 125211_1_online.pdf 1 E8A365C8D358475274A4278BB9A6FF07 17ab4404489c17552a5e0099a72c5a468736a985545f2aaf0fa9258728d55969 b6415bff-0df5-11ef-b552-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=183406 https://aip.scitation.org/doi/full/10.1063/5.0131511 1 8d47ee2e-0df5-11ef-b552-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=183405 Fakulteta za elektrotehniko 0 0 0
