    Abstract

    This thesis reports research carried out to develop a non-averaged 3D simulation code written using minimal approximation to model a Free Electron Laser (FEL) amplifier, the so-called fourth generation light source. Previous generations of light source use synchrotron which has poor temporal coherence. The current race to build the next generation of coherent light sources, FELs, has started and the work carried out in this thesis aims to provide a new simulation code to give insight on the behaviour of the electrons and radiation interaction below the radiation wavelength limit. The numerical simulation was written in Fortran 90 for use on parallel ar- chitecture computers to model a Free Electron Laser in three spatial dimensions and including time dependent e®ects. The Maxwell wave equation and Lorentz equation were used to describe the radiation field evolution and the electrons' propagation. These equations were scaled to become dimensionless. A finite element method, linear solver and Runge{Kutta method were applied to solve these equations.
