Synthetic Diagnostics of Radiation Phenomena in the Particle-in-Cell Code PIConGPU — •Richard Pausch, Michael Bussmann, Heiko Burau, Alexander Debus, Axel Huebl, Arie Irman, Ulrich Schramm, and René Widera — Helmholtz-Zentrum Dresden-Rossendorf

Synthetic diagnostics in particle-in-cell codes provide physical quantities to the scientist that can be directly compared to experiment. We present simulations of laser-wakefield acceleration of electrons and on the dynamics of the relativistic Kelvin-Helmholtz Instability using the code PIConGPU. With PIConGPU it is possible to compute the radiation of every single electron in the simulation caused by acceleration by computing the Lienard-Wiechert Potentials, including both coherent and incoherent radiation. With GPU-accelerated codes Petaflop performance has become possible.
