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.
