TLDR
The Electric and Magnetic Field Instrument and Integrated Science (EMFISIS) investigation on the NASA Radiation Belt Storm Probes (now named the Van Allen Probes) mission provides key wave and very low frequency magnetic field measurements to understand radiation belt acceleration, loss, and transport.Abstract:
The Electric and Magnetic Field Instrument and Integrated Science (EMFISIS) investigation on the NASA Radiation Belt Storm Probes (now named the Van Allen Probes) mission provides key wave and very low frequency magnetic field measurements to understand radiation belt acceleration, loss, and transport. The key science objectives and the contribution that EMFISIS makes to providing measurements as well as theory and modeling are described. The key components of the instruments suite, both electronics and sensors, including key functional parameters, calibration, and performance, demonstrate that EMFISIS provides the needed measurements for the science of the RBSP mission. The EMFISIS operational modes and data products, along with online availability and data tools provide the radiation belt science community with one the most complete sets of data ever collected.read more

Butterfly distribution of Earth’s radiation belt relativistic electrons induced by dayside chorus
TL;DR: In this paper, the authors reported correlated Van Allen Probes data on wave and particle during the 11-13 April, 2014 geomagnetic storm and found that a butterfly pitch angle distribution of relativistic electrons is formed around the location L = 4.52, corresponding to the presence of enhanced dayside chorus.

TL;DR: In this article, the Van Allen Probes encountered multiple geomagnetic storms and simultaneously observed intensified chorus and hiss waves during 18 February to 2 March 2014, and showed that the interplay between both competing mechanisms of chorus-driven acceleration and the hiss-driven scattering often occurs in the outer radiation belts.

Regular Article: A Solution-Adaptive Upwind Scheme for Ideal Magnetohydrodynamics
TL;DR: In this article, the authors present a computational scheme for compressible magnetohydrodynamics (MHD) based on the same elements that make up many modern compressible gas dynamics codes: high-resolution upwinding based on an approximate Riemann solver for MHD and limited reconstruction; an optimally smoothing multi-stage time-stepping scheme; and solution-adaptive refinement and coarsening.

Relativistic theory of wave‐particle resonant diffusion with application to electron acceleration in the magnetosphere
TL;DR: In this paper, a model was proposed to account for the observed variations in the flux and pitch angle distribution of relativistic electrons during geomagnetic storms by combining pitch angle scattering by intense EMIC waves and energy diffusion during cyclotron resonant interaction with whistler mode chorus outside the plasmasphere.

Pitch-angle diffusion of radiation belt electrons within the plasmasphere.
TL;DR: In this paper, the formation of the quiet-time electron slot, which divides the radiation belt electrons into an inner and an outer zone, was investigated. But the results were limited to the inner radiation zone.
