Modeling electron microburst induced by chorus waves

Abstract

The interaction of chorus waves with energetic electrons is investigated using test particle simulation, for two cases respectively, one (for a ducted chorus) with an assumption of parallel propagation along a dipole field line (Figure 1), and the other one (for an unducted chorus) with a more physical wave propagation in the dipole field. F or the latter case, ray tracing of many waves is used to reconstruct the spatial and temporal variation of electromagnetic field of chorus elements. Substantial differences in electron transport are found and signatures of electron precipitation pattern induced by the chorus waves are predicted.
