THPMR034  Simulation of Single Particle Dynamics in a Compact Planar Wiggler  3458 


In this report a description of a simple approach how to simulate a single particle track in a 3D magnetic field using Radia code is presented. Such a simulation maybe useful in order to briefly estimate in a short time the beam dynamics in the magnetic field produced by means of different types of the magnet devices. As an example, a low energy relativistic electron tracking* is performed in a compact 30 cm planar wiggler which produced ~0.4 T magnetic field. The changes of the electron entrance point and motion direction are also available. This simulation is carried out using threedimensional magnetostatic code  Radia**, where the 4th order RungeKutta method was implemented for the trajectory calculations. Since Radia is the Mathematica addon then a small Wolfram Language code is developed to create the wiggler model, to calculate the electron trajectory and to illustrate the simulation results.
