Simulating a one-dimensional plasma
A plasma is an ionized gas in which some of the electrons are free rather than bound to atoms as in an ordinary gas. The behavior of a plasma is more subtle than the behavior of an ordinary gas. In an ordinary gas the dynamics is dominated by two-body collisions, but in a plasma the particles interact via long-range forces, and this interaction causes the plasma to exhibit collective effects. I...
متن کاملOne-dimensional Models of Stationary Plasma Thruster
A stationary plasma thruster (SPT, or Hall Thruster) is an electromagnetic thruster whose properties make it especially suitable for applications such as satellite station-keeping. Fig. 1 represents schematically the geometry of the SPT. Xenon is injected from the anode (rate on the order of 5mg/s), at the end of the dielectric cylinders and on the cathode side, outside the cylinders. We are ma...
متن کاملNormal modes of a quasi-one-dimensional multichain complex plasma.
We studied equally charged particles, suspended in a complex plasma, which move in a plane and interact with a screened Coulomb potential (Yukawa type) and with an additional external confining parabolic potential in one direction, which makes the system quasi-one-dimensional (Q1D). The normal modes of the system are studied in the presence of dissipation. We also investigated how a perpendicul...
متن کاملA Scheme for Simulating One-dimensional Diffusion Processes with Discontinuous Coefficients
The aim of this article is to provide a scheme for simulating diffusion processes evolving in one-dimensional discontinuous media. This scheme does not rely on smoothing the coefficients that appear in the infinitesimal generator of the diffusion processes, but uses instead an exact description of the behavior of their trajectories when they reach the points of discontinuity. This description i...
متن کاملStability of one-dimensional relativistic laser plasma envelope solitons
Stability of one dimensional relativistic laser plasma envelope solitons formed by the nonlinear coupling of relativistically intense electromagnetic waves with plasma waves in a cold plasma to has been examined using fluid simulations. It is observed that the solutions for which scalar potential is weaker than the vector potential are stable whereas solutions with comparatively much higher sca...
