2D3V kinetic simulation of Hall effect thruster, including azimuthal waves and diamagnetic effect

Abstract: Axial-azimuthal (2D3V) full-kinetic PiC+MCC-model was built to simulate dynamics of Hall effect thruster discharge plasma taking into account azimuthal waves and diamagnetic effect. The transition from ignition to the steady-state regime was simulated. Calculation of discharge ignition shows a significant distortion in the shape of the magnetic field caused by high azimuthal-drift current. This effect and intensive ionization lead to the fact that full potential drop localizes in a thin non-magnetized cathode … Show more

“…The TTB code described in the article is based on the idea of a weak anisotropy of the eEDF in the electric field, which makes it possible to take into account only the first two terms of the eEDF decomposition in the energy space, i.e., to perform linearization of eEDF, and implements the solution of the non-stationary BKE. The MCC code takes its origin from the ΘHall PiC+MCC code described before in [36,37]. The Monte-Carlo module was heavily modified and rewritten to support an arbitrary set of reactions and active/background components.…”

“…Therefore, the change in the discharge current is mainly concerned with the electron cross-field transport. However, the electron dynamics in Hall thrusters is sensitive to a lot of factors, such as the magnitude and shape of the magnetic field [34,35], the electron-wall interaction [36], and the discharge oscillation [37]. Plenty of works have been performed so far to investigateelectron cross-field transport in the strong magnetic field region of unshielded Hall thrusters; unfortunately, the involved mechanism is far from being understood [38].…”

“…For the sake of establishing a coordinate system, we utilize a straight line where the outer magnetic pole intersects with the outer wall surface of the channel, denoting them as the r-axis and z-axis, respectively. The center points of the 16 magnetic sensors are cataloged as: (20,10), (30,10), (40, 10), (50, 10), (30,20), (40, 20), (50, 20), and (45, 30). At each of these positions, a pair of magnetic sensors are strategically placed perpendicular to one another, designed to measure both axially and radially.…”
