Abstract

The dynamics of electrons with energies from hundreds of keV to tens of MeV were simulated in a dipole magnetic field. A uniform convection electric field was superimposed. Energetic electrons can be injected into the inner magnetosphere around midnight at the onset of the substorm expansion phase. These electrons proceed to drift eastward towards dawn. Energy dispersion is expected because of their different drift velocities. The model was used to simulate the evolution of the energy, radial distance (L shell) and pitch angle distribution function with local time. The results of the simulations are compared to experimental observations from geosynchronous satellites.
