Modelling the outer radiation belt as a complex system in a self-organised critical state [PDF]

Nonlinear Processes in Geophysics, 2005
The dynamic behaviour of the outer electron radiation belt makes this area of geo-space a candidate for the concept of self-organized criticality. It is shown here that frequency distributions of measured outer electron radiation belt data are well ...

Magnetic field at geosynchronous orbit during high-speed stream-driven storms: Connections to the solar wind, the plasma sheet, and the outer electron radiation belt [PDF]

, 2010
Superposed-epoch analysis is performed on magnetic field measurements from five GOES spacecraft in geosynchronous orbit during 63 high-speed stream-driven storms in 1995–2005. The field strength and the field stretching angle are examined as functions of

Electron loss rates from the outer radiation belt caused by the filling of the outer plasmasphere: The calm before the storm [PDF]

, 2009
Measurements from seven spacecraft in geosynchronous orbit are analyzed to determine the decay rate of the number density of the outer electron radiation belt prior to the onset of high-speed-stream-driven geomagnetic storms.

A density-temperature description of the outer electron radiation belt during geomagnetic storms [PDF]

, 2010
Bi-Maxwellian fits are made to energetic-electron flux measurements from seven satellites in geosynchronous orbit, yielding a number density (n) and temperature (T) description of the outer electron radiation belt.

Discovery of a transient radiation belt at Saturn [PDF]

, 2008
Radiation belts have been detected in situ at five planets. Only at Earth however has any variability in their intensity been heretofore observed, in indirect response to solar eruptions and high altitude nuclear explosions. The Cassini spacecraft's MIMI/

Investigating radiation belt losses though numerical modelling of precipitating fluxes [PDF]

Annales Geophysicae, 2004
It has been suggested that whistler-induced electron precipitation (WEP) may be the most significant inner radiation belt loss process for some electron energy ranges. One area of uncertainty lies in identifying a typical estimate of the precipitating

Off‐Equatorial Source of Magnetosonic Waves Extending Above the Lower Hybrid Resonance Frequency in the Inner Magnetosphere

Geophysical Research Letters, 2021
Inner magnetospheric magnetosonic waves are usually considered to grow from the near‐equatorial ion Bernstein instability below the lower hybrid resonance frequency and contribute significantly to the radiation belt electron dynamics.

Passive shielding against proton and electron in the inner radiation belt

He jishu, 2023
BackgroundElliptical orbiting satellites passing through the inner radiation belt are exposed to high-energy and high-flux protons and electrons. Therefore, electronic devices of satellites need to resist ultra-high cumulative radiation doses.PurposeThis

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 ...
