Applications of the General Particle Tracer code

The General Particle Tracer (GPT) code provides a new 3D simulation package to study charged particle dynamics in electromagnetic fields. Because of its modern implementation, GPT can be conveniently customized without compromising its ease of use, accuracy or simulation speed. The most common use of GPT is accelerator and beam line design, especially the calculation of non-linear 3D space-charge effects. A typical example is the study of the effect of different bunch charges in a bend system. One of the advanced GPT features is the possibility to solve additional differential equations while tracing particles. Using this mechanism, the generated EM wave power spectra in an undulator and the effect of beam-loading in a traveling wave linac are calculated self-consistently with the particle trajectories.
