The goal is to maintain the electron beam acceleration during the whole propagation of the beam along the accelerator. We consider the 9-cell cavity of the TESLA accelerator shown here.
However, when it comes to the interaction with the beam, the Wakefield solver is an incredibly versatile tool (read more about CST Studio Suite solvers here). Breakdown effects such as multipaction and corona effects can be simulated and, with multiphysics simulation, the thermal and mechanical effects of high-power microwaves can also be taken into account.Īccelerator components such as cavities or beam position monitors are typically designed with the Eigenmode, Transient or Frequency Domain solvers. Magnetrons, gyrotrons, klystrons and traveling wave tube amplifiers are among the components that can be designed with CST Studio Suite. Particle dynamics simulation is also crucial in the design of vacuum electronics devices. These are used to design beamline components from particle sources, to magnets, to cavities, to absorbers.
Besides the typical static and high-frequency solvers, this includes the Particle Tracking Solver, the electrostatic ( Es-PIC) and the standard Particle-in-Cell (PIC) Solver and the Wakefield Solver. The beam is guided by various beam optic devices.ĬST Studio Suite and Opera include several tools for designing charged particle devices. The beam is considered as a current, that creates electromagnetic fields, wake fields that can act back on itself or on following beams. In particular an electron beam can now approach the speed of light, the ultrarelativistic limit. In order to reach higher particle energies the particle beam is exposed to RF-fields. At this point, we require a fully self-consistent Particle-in-Cell simulation. The self-electromagnetic fields can introduce a transient component that acts back on the particles. The particle simulation can consider the fields generated by the particles as space charge which overlays the external electromagnetic fields.
With the increase in the particles energies the relativistic equations of motion are considered. In addition, these devices creating external fields are carefully designed using highly accurate static simulation. The simulation process of a particles life can start with the emission of the particles, the effects of accelerating electrostatic and focusing magnetostatic fields that they are exposed to. This part of the portfolio relies on the well-established technologies provided through CST Studio Suite and Opera.Įlectromagnetic simulation in general and charged particle dynamics simulation in particular are key to analyze and optimize a great variety of charged particle devices. The SIMULIA simulation portfolio comprises a wide range of solvers, enabling the simulation of devices that operate employing the interaction of free moving particles and electromagnetic fields.
