Scientific paper

The Salammbô code, which solves the three-dimensional phase-space diffusion equation for the electron radiation belt, was used to explain the dynamic conditions present during a geomagnetic storm. With a simple injection model, we have characterized the dynamic behavior for relativistic electrons in the outer belt. The particles in the range 100 keV-500 keV are diffused throughout the belt, with a shape essentially dependent on the radial diffusion coefficients. Particles with higher energies are ``created'' by acceleration of slower particles near the plasmapause location. The calculated shape of the fluxes in an L-versus time grid for the 1 MeV electrons looks globally like those measured aboard the CRRES satellite.
