چکیده
LLE Review, Volume 74 113 Laser–plasma instabilities1 are important in the field of inertial confinement fusion2 because they scatter laser light away from the target, which reduces the laser energy available to drive the compression of the nuclear fuel, or generate energetic electrons that preheat the fuel, which makes the fuel harder to compress. In stimulated Raman scattering an incident, or pump, light wave (0) decays into a frequency-downshifted, or Stokes, light wave (1) and an electron-plasma wave (2). In stimulated Brillouin scattering a pump light wave decays into a Stokes light wave and an ion-acoustic wave (2). The initial evolution of both instabilities is governed by the linearized equations3

In this article, non-linear Landau damping and generation of BGK mode in non-magnetized plasma are studied by using particle simulation. As plasma environment consists of electrons and ions, it is simulated by particle method and it is supposed that ions are considered as a motionless background. On the other hand, electron’s dynamic is obtained from solving Newton’s equation and the electron...
متن کاملLandau Damping of Surface Plasma Waves
The integral of the kinetic electrostatic surface wave dispersion relation is asymptotically evaluated to determine the frequencies of the normal modes and the corresponding Landau damping for the high frequency surface electron plasma wave and the low frequency surface ion acoustic wave. The asymptotically calculated Landau damping rates apply to the limiting cases of kx e <<1 and kx e >>1 whe...
متن کاملLandau Damping and Transit-Time Damping of Localized Plasma Waves in General Geometries
200 LLE Review, Volume 75 The collisionless damping of electrostatic plasma waves, first predicted by Landau1 in 1946 and since rederived in many ways and confirmed experimentally, has become perhaps the most well known phenomenon in plasma physics. Landau damping plays a significant practical role in many plasma experiments and applications but has continued to be of great interest to theorist...
متن کاملNonlinear Landau Damping of Alfven Waves in a High ß Plasma *
To Professor Arnulf Schlüter on his 60th Birthday A study is made of the nonlinear damping of parallel propagating Alfven waves in a high ß plasma. Two circularly polarized parallel propagating waves give rise to a beat wave, which in general contains both a longitudinal electric field component and a longitudinal gradient in the magnetic field strength. The wave damping is due to the interacti...
متن کاملStudy of Ion Sound Propagation Waves in Thermal Plasma
Plasma can support a great variety of wave motion. Both high frequency and low frequency, electromagnetic and electrostatic waves may propagate in plasma. The primary emphasis has been placed on the study of electrostatic waves because the ease with which such waves may be excited and detected and because the collisionless damping of waves predicted by Landau can be conveniently studied. In thi...
