Relativistic surfatron process for Landau resonant electrons in radiation belts [PDF]

Nonlinear Processes in Geophysics, 2014
Recent theoretical studies of the nonlinear wave-particle interactions for relativistic particles have shown that Landau resonant orbits could be efficiently accelerated along the mean background magnetic field for propagation angles θ in close proximity

Forecasting the Radiation Belts in Europe [PDF]

Space Weather, 2012
Weather forecasting has expanded to space weather. As of 1 March 2012, satellite operators and the general public will be able to obtain forecasts of the Earth’s radiation belts, thanks to the SPACECAST project. The opening of the first European system to forecast Earth’s radiation belts, part of the SPACECAST project, is funded by the European Union ...

Physics of Earth’s Radiation Belts [PDF]

, 2022
This open access book serves as textbook on the physics of the radiation belts surrounding the Earth. Discovered in 1958 the famous Van Allen Radiation belts were among the first scientific discoveries of the Space Age.

Radiation Belts and Their Environment [PDF]

, 2021
AbstractThe Van Allen radiation belts of high-energy electrons and ions, mostly protons, are embedded in the Earth’s inner magnetosphere where the geomagnetic field is close to that of a magnetic dipole. Understanding of the belts requires a thorough knowledge of the inner magnetosphere and its dynamics, the coupling of the solar wind to the ...

NARX Neural Network Derivations of the Outer Boundary Radiation Belt Electron Flux

Space Weather, 2022
We present two new empirical models of radiation belt electron flux at geostationary orbit. GOES‐15 measurements of 0.8 MeV electrons were used to train a Nonlinear Autoregressive with Exogenous input (NARX) neural network for both modeling GOES‐15 flux ...

Using MEPED observations to infer plasma density and chorus intensity in the radiation belts

Frontiers in Astronomy and Space Sciences, 2022
Efforts to model and predict energetic electron fluxes in the radiation belts are highly sensitive to local wave-particle interactions. In this study, we use multi-point measurements of precipitating and trapped electron fluxes to investigate the dynamic

The Radiation Belts of Jupiter and Saturn [PDF]

, 2021
The era of outer planet orbiters (Galileo, Juno and Cassini) is advancing our understanding of how the radiation belts of Jupiter and Saturn are structured, form, and evolve well beyond what had been possible during the age of flyby missions and ground ...

Atmospheric losses of radiation belt electrons [PDF]

Journal of Geophysical Research: Space Physics, 2003
A numerical model of the low‐altitude energetic electron radiation belt, including the effects of pitch angle diffusion into the atmosphere and azimuthal drift, predicts lifetimes and longitude‐dependent loss rates as a function of electron energy and diffusion coefficient.

Design considerations for the use of laser-plasma accelerators for advanced space radiation studies [PDF]

, 2012
We present design considerations for the use of laser-plasma accelerators for mimicking space radiation and testing space-grade electronics. This novel application takes advantage of the inherent ability of laser-plasma accelerators to produce particle ...

Space weather effects on the MAGION-4 and MAGION-5 solar cells [PDF]

Annales Geophysicae, 2005
Data on solar array efficiency measured on board two Czech MAGION micro-satellites between August 1995 and June 2002, during the period of increasing and high solar activity, were used to study the space weather effects on photo-voltaic solar cells. A
