SM22A:
The Role of Small-Scale Mechanisms in the Driving of Particle Energization and Loss in the Inner Magnetosphere and Radiation Belts I


Submit an Abstract to this Session


Session ID#: 61074

Session Description:
In recent years, the role of small-scale (sometimes non-linear) waves/structures in the energization, transport, and loss of charged particles over very broad energy ranges (100 eV to many MeV) in the inner magnetosphere has become a subject of increasing focus. Much of this interest has been motivated by the increased capabilities and discoveries of the Van Allen Probes and Arase spacecraft missions, the BARREL balloon campaign, and low altitude CubeSats. Candidate "waves" include whistler-mode chorus waves, non-linear time domain structures, kinetic Alfven waves, and small-scale electric and magnetic field structures at various boundaries including injection fronts. Particle measurements suggesting processes mediated by these waves include microbursts observed at low altitude, local phase space density peaks, energetic electron precipitation curtains, and a wide variety of distribution functions. This session invites abstracts which include: spacecraft or balloon observations, laboratory plasma results, simulations, or theoretical analysis of any of these phenomena.
