Self-Consistent Effects of Magnetospheric Hydromagnetic Waves on Ring Current Ions
Abstract
The objective of this research in magnetospheric physics was to advance understanding of the interaction of ring current ions with magnetospheric hydromagnetic waves. The goal was to examine the excitation of westward propagating hydromagnetic waves by drift-bounce resonance with 100 to 200 MeV ring current protons using a 3D MHD code in dipole geometry which incorporates the ring current ions via a gyrokinetic treatment. This was the first self-consistent study of this phenomenon. An extension of the ring current particle trajectory tracing code, developed with Air Force support, was used to study the rapid formation of new electron and proton radiation belts. The model has been highly successful at explaining the observed acceleration of electrons and protons by tens of MeV in less than a drift period.
