Galilean electromagnetic particle-in-cell code
Abstract
We introduce a Galilean electromagnetic particle-in-cell (GEM-PIC) algorithm, which transforms the full set of Maxwell equations and the Vlasov equation into the boosted coordinates. This approach preserves the electromagnetic structure of the interaction while exploiting scale separation for computational efficiency. Unlike quasistatic methods, GEM-PIC does not have to distinguish between ”beam” and ”streaming” particles, allowing a self-consistent treatment of particle trapping. The GEM-PIC algorithm allows for highly efficient and accurate simulations of plasma-based wakefield acceleration.
