Efficient models for the electron beam, the severs, and the delay line are investigated to enable accurate and automatable model generation, simulation, as well as pre- and postprocessing. The results of particle-in-cell simulation in CST PS are presented and compared to those of the specialized steady-state simulation codes MVTRAD and KlysTOP, as well as to measurements.0018-9383201862257Journal Article10.1109/TED.2018.2798810Other
