3D gyrotron simulation with CST STUDIO SUITE™

This paper describes the analysis of a 42 GHz gyrotron with the 3D PIC simulation tool CST PARTICLE STUDIO®. Recently implemented features to aid such a simulation are shown. Variation studies concerning B field and beam properties are described. All simulations of the oscillation process are performed using a graphical processing unit (GPU). The results show good agreement to MAGIC simulations.
