Abstract

Energetic electrons are injected into the Earth's inner magnetosphere at the onset of the substorm expansion phase. The electrons proceed to drift eastward towards dawn. The drift process is dispersive, with the result that the injected population becomes spread out in energy and pitch angle. The changing anisotropy of the electron distribution can lead to the spontaneous generation of VLF emissions. Parallel simulations of electron dynamics in the Earth's magnetosphere are used to model the evolution of the injected electron population. The results of the simulations are compared to geosynchronous satellite observations.
