Quasi-linear electron acceleration in a driven plasma wave

Autor: Gérard Gallice, R. Belaouar, Thierry Colin, Vladimir Tikhonchuk

Publikováno v: Plasma Physics and Controlled Fusion. 49:969-984

Saturation of electron plasma waves excited by a spatially localized driver and the electron acceleration in these plasma waves are studied by means of numerical simulations. The model consists of the set of Zakharov equations for the electron plasma

International audience; This article is devoted to the numerical study of a nonlinear Schrödinger equation in which the coefficient in front of the group velocity dispersion is multiplied by a real valued Gaussian white noise. We first perform the n

Theoretical and numerical study of a quasi-linear Zakharov system describing Landau damping

Autor: Cédric Galusinski, Thierry Colin, Gérard Gallice, R. Belaouar

Publikováno v: ESAIM: Mathematical Modelling and Numerical Analysis. 40:961-990

In this paper, we study a Zakharov system coupled to an electron diffusion equation in order to describe laser-plasma interactions. Starting from the Vlasov-Maxwell system, we derive a nonlinear Schrodinger like system which takes into account the en

This paper deals with the numerical simulations of the Vlasov-Poisson equation using a phase space grid in the quasi-neutral regime. In this limit, explicit numerical schemes suffer from numerical constraints related to the small Debye length and lar

In this paper, we present a numerical model for laser-plasma interaction involving Raman instability and Landau damping. This model exhibits three main difficulties. The first one is the coupling of PDE’s posed both in Fourier space and in physical
