Killer Electrons and Phase-Space Lagrangians: Relativistic Electron Dynamics
in Earth’s Magnetosphere

Relativistic (radiation belt) electrons trapped in Earth’s magnetic field
show large flux variations over a wide range of time scales, particularly
during magnetic storms. These electrons are of great scientific interest
because we do not fully understand how they are accelerated to such high
energies. There is also considerable practical interest in these "killer
electrons" because they are potentially hazardous to spacecraft and to
humans in space. In this talk I will briefly present observational and
theoretical background material, and then I will summarize some recent
theoretical work on acceleration and transport processes that play important
roles in the relativistic electron dynamics.
