Abstract

The dimension-free, parallel, plasma simulation code VORPAL, has been used to study laser pulse propagation in Laser Wakefield Acceleration (LWFA). VORPAL is a hybrid code that allows multiple particle models including a cold-fluid model. The fluid model implements a simplified flux corrected transport in the density update but solves the momentum advection directly to allow for simulations of zero density. An implementation of Zalesky's algorithm for FCT is in development. VORPAL simulations predict the rate of loss of energy by pulses propagation through plasma due to Raman scattering. A PIC model for the plasma particles is in development.
