The energization of relativistic electrons in the outer Van Allen radiation belt [PDF]

Nature Physics, 2007
The origin and dynamics of the Van Allen radiation belts is one of the longest-standing questions of the space age, and one that is increasingly important for space applications as satellite systems become more sophisticated, smaller and more susceptible to radiation effects.

Precipitation of Radiation Belt Electrons by EMIC Waves With Conjugated Observations of NOAA and Van Allen Satellites [PDF]

Geophysical Research Letters, 2018
In this letter, we present unique conjugated satellite observations of MeV relativistic electron precipitation caused by electromagnetic ion cyclotron (EMIC) waves. On the outer boundary of the plasmasphere, the Van Allen probe observed EMIC waves.

Quantifying the Size and Duration of a Microburst‐Producing Chorus Region on 5 December 2017 [PDF]

Geophysical Research Letters, 2022
Microbursts are impulsive (30 keV) precipitation (FIREBIRD II and AC6 CubeSats, POES) to determine the size of the microburst‐producing chorus source region beginning on 5 December 2017.

Earth's Van Allen Radiation Belts: From Discovery to the Van Allen Probes Era [PDF]

Journal of Geophysical Research: Space Physics, 2019
AbstractDiscovery of the Earth's Van Allen radiation belts by instruments flown on Explorer 1 in 1958 was the first major discovery of the Space Age. The observation of distinct inner and outer zones of trapped megaelectron volt (MeV) particles, primarily protons at low altitude and electrons at high altitude, led to early models for source and loss ...

The inverse compton effect in the electrons of the Van Allen radiation belt [PDF]

Astrophysics and Space Science, 1970
A first estimate of the energy that reaches the Earth's surface and is produced by the inverse Compton effect between the electrons in the Van Allen belt and the solar flux was made. Since in the belt there are electrons with energies between 0.5 and 7 MeV, it was possible to use the Klein-Nishina formula in an approximate form and estimate the energy ...

Using machine learning to diagnose relativistic electron distributions in the Van Allen radiation belts [PDF]

RAS Techniques and Instruments, 2023
Abstract The behaviour of relativistic electrons in the radiation belt is difficult to diagnose as their dynamics are controlled by simultaneous physical processes, some of which may be still unknown. Signatures of these physical processes are difficult to identify in large amounts of data; therefore, a machine learning approach is ...

A slot region in the magnetosphere of Jupiter [PDF]

Nature Communications
Understanding the balance between charged particle acceleration and loss is central to radiation belt research. Jupiter’s Galilean moons orbit within its intense radiation environment and can act both as sources and sinks of energetic particles.

Outer Van Allen Radiation Belt Response to Interacting Interplanetary Coronal Mass Ejections [PDF]

Journal of Geophysical Research: Space Physics, 2019
AbstractWe study the response of the outer Van Allen radiation belt during an intense magnetic storm on 15–22 February 2014. Four interplanetary coronal mass ejections (ICMEs) arrived at Earth, of which the three last ones were interacting. Using data from the Van Allen Probes, we report the first detailed investigation of electron fluxes from source ...

Dynamics of the inner electron radiation belt: A review

Earth and Planetary Physics, 2023
The Van Allen radiation belts are an extraordinary science discovery in the Earth magnetosphere and consist of two electron belts. The inner Van Allen belt contains electrons of 10s to 100s keV; the outer belt consists mainly of 0.1−10 MeV electrons ...
