Formation of a new radiation belt during October-November storms 2003.
Shprits Y. Y., Thorne R. M., Horne R. ,

Stochastic acceleration and loss of MeV electrons during October-November storms 2003 is required to explain intensive loss and formation of a new radiation belt in the 'slot ' region, near L=3. Filling of the slot region of the radiation belts is modeled with a combined pitch-angle, energy diffusion code. We find that pitch angle distributions attain equilibrium shapes. Energy dependent lifetimes are on the scale of a day for MeV electrons and on the scale of a few hours for keV electron population, which provides a source for chorus emissions. We show that the energy diffusion driven by whistler mode waves is capable of accelerating electrons up to energies of 3 MeV on the time scales of few days which is consistent with Polar and Sampax observations.
