PIC Simulations of PWFA at PITZ using a high order Discontinuous Galerkin Method — Stefan Frank1, Erion Gjonaj2, Andreas Jankowiak3, Gregor Loisch1, Alberto Martinez de la Ossa4, Atoosa Meseck3, Anne Oppelt1, Jens Osterhoff4, and •Valentin Wohlfarth1 — 1DESY Zeuthen, 15738 Zeuthen, Deutschland — 2TEMF TU Darmstadt, 64289 Darmstadt, Deutschland — 3Helmholtz-Zentrum Berlin, 14109 Berlin, Deutschland — 4DESY Hamburg, 22607 Hamburg, Deutschland
Several experiments investigating beam-driven Plasma Wakefield Acceleration (PWFA) are currently conducted at the Photo Injector Test Facility at DESY in Zeuthen (PITZ). So far, Particle-in-Cell (PIC) simulations for the preparation and theoretical evaluation of these experiments have been conducted with HiPACE, a code which is based on Poisson solvers to compute the electromagnetic fields. In this work, a code solving the fields with a high order Discontinuous Galerkin (DG) method [1] is used to reproduce simulations done with HiPACE and the resulting fields and particle beam distributions are compared.
