Abstract

Simulations of a Dielectric Laser Accelerator (DLA) are presented. Where in an electron beam is passed through a double grating structure of a dielectric material, whilst laser light polarized in the direction of travel of the electron beam is applied to both sides. This results in acceleration of the electron beam. The LSP (Large Scale Plasma) code is a particle in cell code which is applied in a novel way to model the DLA. Ultimately answers are needed to the questions: what is the acceleration gradient, how does this depend on the starting energy of the electrons and what is the current that can be accelerated through the DLA? DLA's have great potential in many fields, from providing compact linear accelerators, x-ray light sources and medical devices to high energy particle research.
