Abstract

Since the 1890’s, when a cathode ray tube was able to display images from an electron beam, the acceleration of particles has not only created a deeper understanding of our universe but has also contributed in the research and development of fields such as medicine, chemistry and biology. Particle accelerators, however, tend to be complex, large and extremely expensive to build and maintain. So, in the search of an alternative mechanism for the acceleration of particles, this project theoretically simulates the behaviour of a high intensity laser when accelerating a group of electrons, seeking for a particle resolution able to conserve their calculated momentum and physically sustain the simulations' predicted behavior. In order to achieve this we use EPOCH, a plasma physics simulation code, to run particle-in-cell simulations of 470 electrons accelerated to relativistic velocities by a plane wave electric field.
