Abstract

A laser-plasma-based source of relavistic electrons was analyzed in two dimensions using theoretical and numeric techniques. Two laser beams were focussed in a plasma, one excited a wake-field electron plasma wave while another locally altered some electron trajectories in such a way that they could not be trapped and accelerated by waves. Two-dimensional particle-in-cell simulations and analysis of the single particle trajectories showed that the radial wake field played an important role. The simulation results were interpreted to evaluate the accelerated electron beam's properties and compared with existing devices.
