Lorentz Boosted Frame Simulations of Laser Wakefield Acceleration with the PIC-Code WARP — •Manuel Kirchen1,2, Irene Dornmair1,2, and Andreas Richard Maier1,2 — 1CFEL, Center for Free-Electron Laser Science, 22607 Hamburg, Germany — 2University of Hamburg, Institute of Experimental Physics, 22761 Hamburg, Germany
Research on laser-driven plasma wakefield acceleration has evolved rapidly in the past few decades, demonstrating the generation of quasi-monoenergetic electron beams up to the GeV level in cm-scale targets, using high power laser systems. Particle-In-Cell simulations have become a favourable tool for gaining insights on the complex dynamics of laser-plasma interaction. Yet, they are computation-intensive, hence, a lot of effort is made in reducing the resource consumption of PIC-Codes. A promising approach is to model the interaction in a lorentz-boosted frame. Compensating for the disparity of smallest space (namely the laser wavelength) and time scales (i.e. the interaction length with the plasma), reduces the computational time of the simulation by ≈2 γwake2. However, a back-transformation of the simulation data needs to be performed, in order to get physically interpretable results in the lab frame. Here, we present an efficient output method for boosted frame simulations and the implementation of the process with the PIC-Code WARP.
