Summary:
Energetic particles in the plasma sheet and near-Earth magnetotail can be transported sunward by large-scale magnetospheric convective processes, allowing some populations to be trapped inside the 'Alfven Layer' on close drift paths in the inner magnetosphere. These newly-trapped particles may contribute directly to the seed populations that are subsequently heated to ring current and radiation belt energies, and may also provide a source of free energy for the generation of electromagnetic waves that affect the dynamic variations of the outer radiation belts. In this effort, we propose a study of the dynamics of the Alfven layer and the characteristics and effects and contributions of energetic plasma sheet particles on trapped populations in the inner magnetosphere.Performance Year | Reference | Actions |
