Simulation Techniques for Vacuum Electronic Devices

S. N. Sytova

This article is devoted to overview of principles of simulation the nonlinear processes of radiation emission in different types of vacuum electronic devices. Such devices are travelling wave tubes, backward wave tubes, multiwave Cherenkov generators, free electron lasers and masers, volume free electron lasers (VFEL). In all these devices a charged particle beam moves through a slow wave structure and interacts there with an electromagnetic field. Regarding VFEL simulation, computer code VOLC is considered. It is a tool for VFEL express simulation, being very fast and giving numerical results in reasonable agreement with theoretical and experimental physical results.

Key words: simulation, nonlinear dynamics, vacuum electronic device, volume free electron laser
