A new simulation code for particle diffusion in anisotropic, large-scale and turbulent magnetic fields Original Research Article

A new Monte Carlo code is presented that simulates the scattering processes of energetic particles in turbulent magnetic fields. The growing number of analytical models for anisotropic turbulence geometries gives rise to the need of fast and adaptable simulation codes that, in order to be able to judge the accuracy of the results, calculate the estimated mean errors of the transport parameters. Furthermore, the need to understand the interplay of scattering in anisotropic large-scale (such as the solar magnetic field) and turbulent (such as the Maltese cross-like structured solar wind turbulence) magnetic fields is accounted for with the calculation of the off-diagonal elements of the diffusion tensor.
