Simulation of laser wakefield acceleration of an ultrashort electron bunch.

The dynamics of the acceleration of a short electron bunch in a strong plasma wave excited by a laser pulse in a plasma channel is studied both analytically and numerically in slab geometry. In our simulations, a fully nonlinear, relativistic hydrodynamic description for the plasma wave is combined with particle-in-cell methods for the description of the bunch. Collective self-interactions with...

Characteristics of Electron Acceleration in a Self-modulated Laser Wakefield

Acceleration of electrons by an electron plasma wave has been of great current interest because of its much larger acceleration gradient than that of conventional rf linacs [1]. Several methods have been proposed for driving a largeamplitude fast-phase-velocity plasma wave [1]. In the Laser Wake-Field Accelerator (LWFA), an electron plasma wave is driven resonantly by a short laser pulse throug...

Cosmic Plasma Wakefield Acceleration

Recently we proposed a new cosmic acceleration mechanism which was based on the wakefields excited by the Alfven shocks in a relativistically flowing plasma. In this paper we include some omitted details, and show that there exists a threshold condition for transparency below which the accelerating particle is collision-free and suffers little energy loss in the plasma medium. The stochastic en...
