TL;DR: It is shown, on the basis of the analysis of a rare event where the outer radiation belt was depleted and then re-formed closer to the Earth, that the long established theory of acceleration by radial diffusion is inadequate; the electrons are accelerated more effectively by electromagnetic waves at frequencies of a few kilohertz.

TL;DR: In this article, a sine-wave parametric model with a variable amplitude was used to analyze the lower band of chorus below one half of the electron cyclotron frequency, measured at a radial distance of 4.4 Earth's radii, within a 2000 km long source region located close to the equator.

TL;DR: The POLAR plasma wave instrument often detects coherent electric field structures in the high altitude polar magnetosphere, which are found to move both up and down the ambient magnetic field as mentioned in this paper.

TL;DR: The charge and mass magnetospheric ion composition experiment (CAMMICE) on board the Polar spacecraft observed 75 energetic particle events in 1996 while the satellite was at apogee as discussed by the authors.

TL;DR: In this article, the authors used data from the Cluster spacecraft to characterize propagation and spectral properties of chorus and found that chorus in the source region can be formed by a succession of discrete wave packets with decreasing frequency that sometimes change into shapeless hiss.
