“Pancake” electron distributions in the outer radiation belts [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 1999
Electron pitch angle distributions sharply peaked at 90° pitch angle were first recorded in the energy range 50 eV < E < 500 eV by the GEOSl and GEOS2 spacecraft in 1977/1978, from the plasmapause out to geostationary orbit. At the time they were explained as the remnants of pitch angle diffusion driven solely by electron cyclotron harmonic (ECH)

The 600 keV electron injections in the Earth’s outer radiation belt: A statistical study

open access: yesEarth and Planetary Physics, 2022
Relativistic electron injections are one of the mechanisms of relativistic (≥0.5 MeV) electron enhancements in the Earth’s outer radiation belt. In this study, we present a statistical observation of 600 keV electron injections in the outer radiation ...

Energy spectrum of electrons in the outer radiation belt [PDF]

open access: yesJournal of Geophysical Research, 1962
The equilibrium energy spectrum of electrons in the outer radiation belt is determined by the injection spectrum and the loss processes that operate to remove the electrons or change their energy. The loss processes considered here are ionization energy loss, multiple scattering, and electron-electron scattering; the injection spectra considered are ...

Multi‐MeV electron loss in the heart of the radiation belts [PDF]

open access: yesGeophysical Research Letters, 2017
AbstractSignificant progress has been made in recent years in understanding acceleration mechanisms in the Earth's radiation belts. In particular, a number of studies demonstrated the importance of the local acceleration by analyzing the radial profiles of phase space density (PSD) and observing building up peaks in PSD.

Off-equatorial effects of the nonlinear interaction of VLF chorus waves with radiation belt electrons

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Nonlinear processes are involved in both the growth of VLF chorus waves and the energization of radiation belt electrons trapped in the wave potential. Nonlinear theory has led to analytic formulae describing both these processes.

Controlled precipitation of radiation belt electrons [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2003
First‐order estimates indicate that the lifetime of energetic (a few MeV) electrons in the inner radiation belts (e.g., near L = 2) may be significantly reduced by in situ injection of whistler mode waves at radiated power levels of a few kW at frequencies of a few kHz.

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Comparison of radiation belt electron fluxes simultaneously measured with PROBA-V/EPT and RBSP/MagEIS instruments [PDF]

open access: yesAnnales Geophysicae, 2023
Relativistic radiation belt electron observations from the Energetic Particle Telescope (EPT) on board the PROBA-V (Project for On-Board Autonomy and Vegetation) satellite are compared to those performed by the Magnetic Electron Ion Spectrometer (MagEIS)

Electron radiation belts of the solar system [PDF]

open access: yesJournal of Geophysical Research: Space Physics, 2010
To address factors dictating similarities and differences between solar system radiation belts, we present comparisons between relativistic electron radiation belt spectra of all five strongly magnetized planets: Earth, Jupiter, Saturn, Uranus, and Neptune.

Analysis of radiation belt killer electron energy spectra

open access: yesProceedings of the XXXVth URSI General Assembly and Scientific Symposium – GASS 2023, 2022
AbstractHighly energetic (>1 MeV) electrons are typically generated in the Earth's outer radiation belt during geomagnetically disturbed times. Such “killer” electrons can be produced by electron cyclotron resonance with whistler‐mode waves. We model this process by a relativistic Fokker‐Planck diffusion equation for the electron distribution ...
