Description
We discuss the dynamics of the radiation belts by launching electrons and protons in the inner magnetosphere and investigate the trajectory of the particles. A hot issue today concerning radiation belts is the question if there are relativistic electrons in the inner belt. The observations of relativistic electrons in the inner belt and the South Atlantic Anomaly are possibly caused by proton contamination. We discuss the distinct properties of the gyromotion trajectories of electrons with energies from 0.5 to 20 MeV and protons with energies from 9.5 to 300 MeV. We discuss adiabatic invariants, gyrofrequency, gyroradius, bouncefrequency, driftfrequency, and pitch angle distributions of the electrons and the protons at spacecraft orbits, like LEO and GEO.
