We show how to simulate electromagnetic radiation from plasmas using the particle-in-cell code PIConGPU. After an introduction of the methods we present results from Laser-Wakefield simulations and a large scale Kelvin-Helmholtz-simulation (7.2 PFLOP/s) performed on the TITAN cluster in Oakridge. Towards the conclusion we show that these methods also translate to modeling optical free-electron lasers based on Traveling-wave Thomson scattering. (This is a summary, as there was no official abstract.)

Keywords: plasma radiation; laser wakefield acceleration; LWFA; Kelvin-Helmholtz instability; KHI; Traveling-wave Thomson scattering; TWTS; optical free-electron laser
