Slides and handouts of the "power point presentation" given 14 September 2009
by J. Lemaire at the "Earth and Jupiter Radiation Belts" session of the EPSC in Potsdam
It is indicated how the variation of the electron Radiation Belt fluxes observed at low altitude
may be explained by combining the standard betatron acceleration mechanism with concomitent
non-resonant pitch angle scattering during geomagnetic storms.
The handouts contain also good reason to use McIlwain's L-coordinate, instead of Roederer's L-coordinate
in future Radiation Belt modelling activities.
