Electro Acceleration in a Geomagnetic Field Line Resonance
[report]
2012
unpublished
A hybrid MHD kinetic electron model in dipolar coordinates is used to simulate the upward current region of a geomagnetic Field Line Resonance (FLR) system for a realistic ambient electron temperatures of a keV. It is found that mirror force effects result in potential drops sufficient to accelerate electrons to energies in excess of a keV in support of field aligned currents on the order of 0.5 µA/m 2 . The wave energy dissipated in this acceleration would completely damp an undriven FLR with
