Electron dynamics simulations with Hellweg 2D code

In this paper Hellweg 2D code is introduced. It is a special tool for electron dynamics simulation in waveguide travelling wave accelerating structure. The underlying theory of this software is based on the differential equations of motion. The effects considered in this code include beam loading, space charge forces and external magnetic field. Hellweg 2D is capable of dealing with multisectional accelerators. Along with the analysis of electron linacs, this program is able to synthesize accelerating structures. This paper provides the comparison of the PARMELA, Hellweg 2D and experimental data of the existing facilities. The results of beam dynamics simulation in a hybrid accelerator with a standing wave (SW) buncher and travelling wave (TW) regular section are presented.
