Electron Acceleration in the Heart of the Van Allen Radiation Belts

Science, 2013
Local Acceleration How the electrons trapped in Earth-encircling Van Allen radiation belts get accelerated has been debated since their discovery in 1958. Reeves et al. (p.

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

The geomagnetic cavity and the Van Allen radiation belts—II

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.

The Upper Boundary of the Van Allen Radiation Belts. [PDF]

Nature, 1959
THREE measurements have now been made of the intensity and extent of the Earth's upper radiation belt and of the primary cosmic-ray intensity beyond. These were made by: (1) the American space probe, Pioneer III (December 6–7, 1958, ref. 1), (2) the Russian cosmic rocket, Mechta (January 2–4, 1959, ref. 2), and (3) the American space probe, Pioneer IV (

The Stability of the Van Allen Radiation Belt

SIAM Journal on Applied Mathematics, 1979
In this paper we derive two classes of invariant tori which lie on energy surfaces which are large enough to accommodate the charged particles in the Van Allen radiation belt.

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.
