Maximum total energy of the Van Allen radiation belt

Journal of Geophysical Research, 1960
It is the purpose of this letter to point out that the results of the spherical harmonic analysis of the geomagnetic field place an upper limit on the energy that can be stored in the Van Allen radiation belt. It will be shown that conservative figures indicate a maximum energy in trapped radiation of 6×1015 joules.

An impenetrable barrier to ultrarelativistic electrons in the Van Allen radiation belts

Nature, 2014
Early observations indicated that the Earth's Van Allen radiation belts could be separated into an inner zone dominated by high-energy protons and an outer zone dominated by high-energy electrons. Subsequent studies showed that electrons of moderate energy (less than about one megaelectronvolt) often populate both zones, with a deep 'slot' region ...

Measurement of radiation in the lower Van Allen belt

Journal of Geophysical Research, 1960
In the first of a series of experiments, an instrument package of eight Geiger counters, shielded and collimated in various ways, was carried aloft and released by an Atlas ICBM; its trajectory passed into the lower Van Allen radiation belt. Since there are variations in altitude at the isocount contours of the belt at several latitudes, the trajectory

Electron Flux Variability and Ultra‐Low Frequency Wave Activity in the Outer Radiation Belt Under the Influence of Interplanetary Coronal Mass Ejections and High‐Speed Solar Wind Streams: A Statistical Analysis From the Van Allen Probes Era

Journal of Geophysical Research: Space Physics, 2022
The ultra‐low frequency (ULF) waves can stochastically accelerate radiation belt electrons. Radial diffusion is a well‐established mechanism that can enhance or reduce the electron population in combination with other processes.

Inner-belt Van Allen radiation

Space Science Reviews, 1969
A survey of the present state of knowledge about the inner radiation zone is presented. This includes a historical review of empirical data and theoretical considerations concerning electrons, protons, and heavier particles. Included are results obtained from the various high-altitude nuclear tests.

The geomagnetic cavity and the Van Allen radiation belts

Planetary and Space Science, 1966
Using the spherical harmonic expansion given by Mead for the magnetic field created by the currents on the surface of the geomagnetic cavity, the nature of the trapping regions has been discussed. It is shown that to a first order of approximation in the expansion coefficients, the allowed regions are still determined by a cubic equation.
