Ion resonance acceleration by dipolarization fronts: analytic theory and spacecraft observation

Ion resonance acceleration by dipolarization fronts: analytic theory and spacecraft observation

In this paper, we consider the mechanism of ion acceleration by dipolarization fronts in the Earth's magnetotail. The statistics of dipolarization front observations by Interball-tail have been collected from 1995 to 1998 (51 events). We demonstrate that near dipolarization fronts bursts o...
