Intense chorus waves are the cause of flux-limiting in the heart of the outer radiation belt [PDF]
Scientific Reports, 2022 Chorus waves play a key role in outer Van Allen electron belt dynamics through cyclotron resonance. Here, we use Van Allen Probes data to reveal a new and distinct population of intense chorus waves excited in the heart of the radiation belt during the ...

Wave–particle interaction effects in the Van Allen belts [PDF]
Earth, Planets and Space, 2021 Discovering such structures as the third radiation belt (or “storage ring”) has been a major observational achievement of the NASA Radiation Belt Storm Probes program (renamed the “Van Allen Probes” mission in November 2012).

Impact of the South Atlantic Anomaly on radiation exposure at flight altitudes during solar minimum [PDF]
Scientific Reports, 2023 The South Atlantic Anomaly (SAA) is a geographical region over the South Atlantic Ocean where the inner Van Allen radiation belt extends down particularly close to Earth.

Unusual stable trapping of the ultrarelativistic electrons in the Van Allen radiation belts [PDF]
Nature Physics, 2013 The Van Allen radiation belts are two rings of charged particles encircling the Earth. Therefore the transient appearance in 2012 of a third ring between the inner and outer belts was a surprise. A study of the ultrarelativistic electrons in this middle ring reveals new physics for particles above 2 MeV.

Electron acceleration in the Van Allen radiation belts by fast magnetosonic waves [PDF]
Geophysical Research Letters, 2007 Local acceleration is required to explain electron flux increases in the outer Van Allen radiation belt during magnetic storms. Here we show that fast magnetosonic waves, detected by Cluster 3, can accelerate electrons between ∼10 keV and a few MeV inside the outer radiation belt.

Wave-induced loss of ultra-relativistic electrons in the Van Allen radiation belts [PDF]
Nature Communications, 2016 AbstractThe dipole configuration of the Earth’s magnetic field allows for the trapping of highly energetic particles, which form the radiation belts. Although significant advances have been made in understanding the acceleration mechanisms in the radiation belts, the loss processes remain poorly understood.

Discovery of the action of a geophysical synchrotron in the Earth’s Van Allen radiation belts [PDF]
Nature Communications, 2013 The processes influencing the Van Allen belt – a layer of charged particles inside the Earth’s magnetosphere – are poorly understood. Using CRRES and NASA’s Van Allen Probes data, Mann et al. suggest that ultra-low frequency waves may play a larger role in accelerating particles than previously thought.

Evidence of Microbursts Observed Near the Equatorial Plane in the Outer Van Allen Radiation Belt
Geophysical Research Letters, 2018 We present the first evidence of electron microbursts observed near the equatorial plane in Earth's outer radiation belt. We observed the microbursts on 31 March 2017 with the Magnetic Electron Ion Spectrometer and Radiation Belt Storm Probes Ion ...
