|CST PARTICLE STUDIO® (CST PS) is a specific tool for the fast and accurate analysis of charged particle dynamics and vacuum tubes in 3D electromagnetic fields. This software tool is based on the multi-purpose 3D EM modules in CST STUDIO SUITE such as the CST EM STUDIO electro and magneto static solver. It is fully embedded in CST DESIGN ENVIRONMENT, thus benefitting from its intuitive modeling capabilities and powerful import interfaces. CST PS is based on the knowledge, research and development that went into the algorithms used in the MAFIA-4 simulation package. High Performance Computation (HPC) is also available, therefore pushing the boundaries of complexity and size of the models.
