Description
The transport of charged particles in the heliosphere and the interstellar medium is governed by the interaction of particles and magnetic irregularities. For the transport of protons a rather simple model using a linear Alfven wave spectrum which follows the Kolmogorov distribution usualy yields good results. Even magnetostatic spectra may be used.
For the case of electron transport, particles will resonate with the high-k end of the spectrum. Here the magnetic fluctuations do not follow the linear dispersion relation, but the kinetic regime kicks in. We will discuss the interaction of fluctuations of dispersive waves in the kinetic regime using a particle-in-cell code (Kilian et al. 2012). Especially the scattering of particles following the idea of Lange et al. (2013) and its application to PiC codes (Schreiner & Spanier 2014) will be discussed.
The effect of the dispersive regime on the electron transport will be discussed in detail.
