Science Goals and Overview of the Radiation Belt Storm Probes (RBSP) Energetic Particle, Composition, and Thermal Plasma (ECT) Suite on NASA’s Van Allen Probes Mission [PDF]

, 2013
The Radiation Belt Storm Probes (RBSP)-Energetic Particle, Composition, and Thermal Plasma (ECT) suite contains an innovative complement of particle instruments to ensure the highest quality measurements ever made in the inner magnetosphere and radiation

The discovery of trapped energetic electrons in the outer cusp [PDF]

, 1998
We report on the POLAR/CEPPAD discovery of a trapped, 60°\u3cθ\u3c120° pitch angle electron population in the outer cusp (7−9+ Re), whose energetic electron component extends from below 30 keV to ∼2 MeV.

Modeling inward diffusion and slow decay of energetic electrons in the Earth\u27s outer radiation belt [PDF]

, 2015
A new 3-D diffusion code is used to investigate the inward intrusion and slow decay of energetic radiation belt electrons (\u3e0.5 MeV) observed by the Van Allen Probes during a 10 day quiet period on March 2013.

Satellite observations of lightning-induced hard X-ray flux enhancements in the conjugate region [PDF]

Annales Geophysicae, 2006
Preliminary examination of October-December 2002 SONG (SOlar Neutron and Gamma rays) data aboard the Russian CORONAS-F (Complex Orbital Near-Earth Observations of the Activity of the Sun) low-altitude satellite has revealed many X-ray enhanced ...

Asymmetries in Saturn's radiation belts [PDF]

Journal of Geophysical Research: Space Physics, 2010
We present both energetic proton and electron data from the main radiation belts of Saturn. When organized by L shell and equatorial pitch angle, data from Cassini's Magnetospheric Imaging Instrument reveal proton radiation belts that are highly symmetric in local time. The energetic electron radiation belts are asymmetric in two principal ways.

What happens when the geomagnetic field reverses?

, 2012
During geomagnetic field reversals the radiation belt high-energy proton populations become depleted. Their energy spectra become softer, with the trapped particles of highest energies being lost first, and eventually recovering after a field reversal ...

Low-density plasma as a key catalyst for electron acceleration in the Van Allen radiation belts

Communications Physics
The near-Earth space environment is populated by the most energetic electrons with velocities very close to the speed of light, reaching ultra-relativistic energies.

DOSIS & DOSIS 3D: radiation measurements with the DOSTEL instruments onboard the Columbus Laboratory of the ISS in the years 2009–2016

Journal of Space Weather and Space Climate, 2017
The natural radiation environment in Low Earth Orbit (LEO) differs significantly in composition and energy from that found on Earth. The space radiation field consists of high energetic protons and heavier ions from Galactic Cosmic Radiation (GCR), as ...

The magnetic field of the radiation belts [PDF]

Journal of Geophysical Research, 1962
>The magnetic fields produced by various types of belts of trapped particles are shown graphically. The values of the parameters that determine the field were chosen to cover a wide range. By interpolating the diagrams the distortion of the earth's field can be approximately estimated for actually observed belts without a large amount of computation ...

Helium, Oxygen, Proton, and Electron (HOPE) Mass Spectrometer for the Radiation Belt Storm Probes Mission [PDF]

, 2013
The HOPE mass spectrometer of the Radiation Belt Storm Probes (RBSP) mission (renamed the Van Allen Probes) is designed to measure the in situ plasma ion and electron fluxes over 4π sr at each RBSP spacecraft within the terrestrial radiation belts.
