Autor: Victor Désangles, Sergey Shcherbanev, Thomas Charoy, Noé Clément, Clarence Deltel, Pablo Richard, Simon Vincent, Pascal Chabert, Anne Bourdon
Publikováno v: Atmosphere, Vol 11, Iss 5, p 518 (2020)
Even after half a century of development, many phenomena in Hall Effect Thrusters are still not well-understood. While numerical studies are now widely used to study this highly non-linear system, experimental diagnostics are needed to validate their

Two-dimensional effects on electrostatic instabilities in Hall thrusters. II. Comparison of particle-in-cell simulation results with linear theory dispersion relations
Autor: Federico Petronio, Thomas Charoy, Alejandro Alvarez Laguna, Anne Bourdon, Pascal Chabert
Publikováno v: Physics of Plasmas. 30:012104
In Paper I, we successfully used an external circuit to significantly damp the Breathing Mode (BM) oscillations in 2D particle-in-cell self-consistent simulations of the axial–azimuthal plane of a Hall thruster. We also introduced the two-point pow

Two-dimensional effects on electrostatic instabilities in Hall thrusters. I. Insights from particle-in-cell simulations and two-point power spectral density reconstruction techniques

Using 2D particle-in-cell (PIC) simulations coupled to a fluid description of the gas dynamics, we study the electrostatic instabilities developing in the axial–azimuthal plane of a Hall thruster, during several periods of a low-frequency oscillati

Conditions of appearance and dynamics of the modified two-stream instability in E × B discharges
Autor: Alejandro Alvarez-Laguna, Federico Petronio, Anne Bourdon, Pascal Chabert, Thomas Charoy, Antoine Tavant
Publikováno v: Physics of Plasmas
Physics of Plasmas, American Institute of Physics, 2021, 28 (4), pp.043504. ⟨10.1063/5.0046843⟩
The large differential drift motion between electrons and ions that is created by the E × B current can produce different instabilities, such as the electron cyclotron drift instability, perpendicular to the magnetic field, and the Modified Two-Stre

Collisionless ion modeling in Hall thrusters: analytical axial velocity distribution function and heat flux closures
Autor: Thierry Magin, A. Alvarez Laguna, Anne Bourdon, Thomas Charoy, Stefano Boccelli, Pascal Chabert
Publikováno v: Physics of Plasmas
Physics of Plasmas, American Institute of Physics, 2020, 27 (7), pp.073506. ⟨10.1063/5.0006258⟩
The genesis of the ion axial velocity distribution function (VDF) is analyzed for collisionless Hall thruster discharges. An analytical form for the VDF is obtained from the Vlasov equation, by applying the Tonks–Langmuir theory in the thruster cha

In this paper we propose a representative simulation test-case of E B discharges accounting for plasma wall interactions with the presence of both the electron cyclotron drift instability and the modified-two-stream-instability. Seven independently d
