Abstract The research pivots around the development of a plasma simulation code based on the wave-kinetic paradigm. In this approach, braodband waves in a - plasma are regarded as a distribution of incoherent modes which are treated as particles in the code. The code solves the evolution of EM fields interacting with plasmas, as in laser-wakefield experiments. Following the wave-kinetic approach, the electromagnetic fields are converted into a quasiparticle (photon) distribution; this distribution obeys a Vlasov-like equation. The code solves the evolution of this equation using the particle-in-cell model. This comes down to representing the electromagnetic Fields bya distribution of photons, and tracking their propagation through an optically dispersive medium (the plasma). This approach has been shown to be particularly useful for the study of complex types of wave-plasma interaction, such as four wave modulational instabilities, electromagnetic solution formation, photon acceleration and turbulence, and photon landau damping. There are strong indications that the code can also be employed to tackle a wide spectrum of problems involving turbulence in plasmas and other media. At the moment, the code can do 1-D simulations, and 2-D simulations to a limited extend. Work is under way to extend it to do full 2-D and 3-D simulations. Among other things, it will be necessary to parallellize the code, so it can be run on multiprocessor computer systems. Once this has been realized, the code will be run on the UCLA Super Cluster, one of the fastest computer systems in the world. Section 1-
