Abstract: Abstract The dynamic of the heliosphere is governed by plasma turbulence. Furthermore, charged high-energy particles are generated by coronal mass ejections and shock acceleration. In order to understand these complex dynamics and be able to predict the transport of high-energy particles in future, numerical simulations are the method of choice. We present a hybrid simulation code, which is capable of modelling such a system. According to the theories by Goldreich and Sridhar, the turbulence cascade is anisotropic. This is validated by our simulation results. Furthermore, we show the importance of amplified wave modes to the particle scattering. The limits of quasilinear theory of particle transport are discussed and tools for the interpretation of resonance patterns are presented.
