We consider the development of an efficient numerical method for the simulation of microwave discharge plasmas. The method uses the idea of finite element patch and can deal with very disparate length scales of the plasma. In this paper, the time-dom

L’intérêt d’utiliser des particules chargées accélérées à de grandes vitesses pour propulser un engin spatial a germé dans la tête de C. Tsiolkovski (1857-1935), qui a posé les fondements de l’astronautique dans son ouvrage de 1903. I

Ionization waves (striations) in a low-current plasma column revisited with kinetic and fluid models

Autor: Jean-Pierre Boeuf

A one-dimensional Particle-In-Cell Monte Carlo Collisions (PIC-MCC) method has been used to model the development and propagation of ionization waves in neon and argon positive columns. Low current conditions are considered, i.e. conditions where ste

International audience; This paper provides perspectives on recent progress in understanding the physics of devices in which the external magnetic field is applied perpendicular to the discharge current. This configuration generates a strong electric

Rotating Spokes, Ionization Instability, and Electron Vortices in Partially Magnetized E×B Plasmas

Autor: Jean-Pierre Boeuf, Masayuki Takahashi

Publikováno v: Physical Review Letters. 124

Regions of enhanced light emission rotating in the azimuthal direction are present in various E×B plasma devices. A kinetic model reveals that these "rotating spokes" are due to electron heating and enhanced ionization localized along a double layer
