Differentiating Between the Leading Processes for Electron Radiation Belt Acceleration

Frontiers in Astronomy and Space Sciences, 2022
Many spacecraft fly within or through a natural and variable particle accelerator powered by the coupling between the magnetosphere and the solar wind: the Earth’s radiation belts.

A model of the secondary radiation belt [PDF]

Journal of Geophysical Research: Space Physics, 2008
Products of nuclear reactions between primary radiation belt protons and constituents of the tenuous upper atmosphere form a collocated secondary radiation belt. A calculation of the time‐dependent secondary intensity provides a model specification of this environmental component for low‐ and medium‐altitude satellite orbits.

Radiation belt electron scattering by whistler-mode chorus in the Jovian magnetosphere: Importance of ambient and wave parameters

Earth and Planetary Physics, 2018
Whistler-mode chorus waves are regarded as an important acceleration mechanism contributing to the formation of relativistic and ultra-relativistic electrons in the Jovian radiation belts.

Dependence of Energetic Electron Precipitation on the Geomagnetic Index Kp and Electron Energy [PDF]

Journal of Astronomy and Space Sciences, 2013
It has long been known that the magnetospheric particles can precipitate into the atmosphere of the Earth. In this paper we examine such precipitation of energetic electrons using the data obtained from low-altitude polar orbiting satellite ...

The origin of Jupiter's outer radiation belt [PDF]

Journal of Geophysical Research: Space Physics, 2014
AbstractThe intense inner radiation belt at Jupiter (>50 MeV at 1.5 RJ) is generally accepted to be created by radial diffusion of electrons from further away from the planet. However, this requires a source with energies that exceed 1 MeV outside the orbit of the moon Io at 5.9 RJ, which has never been explained satisfactorily.

Distribution of Seed Electron Phase Space Density Minima in Earth's Radiation Belts

Geophysical Research Letters
We conducted a statistical analysis of local phase space density (PSD) minima across a wide energy range (∼20 keVs to ∼10 MeV), using observations from the Van Allen Probes and the Geostationary Operational Environmental Satellite.

The Chandra X-Ray Observatory's Radiation Environment and the AP-8/AE-8 Model

, 2000
The Chandra X-ray Observatory (CXO) was launched on July 23, 1999 and reached its final orbit on August 7, 1999. The CXO is in a highly elliptical orbit, approximately 140,000 km x 10,000 km, and has a period of approximately 63.5 hours (~ 2.65 days). It

Atmospheric Secondary Particles In Near Earth Space [PDF]

, 2000
The Alpha Magnetic Spectrometer detects a large amount of particles below rigidity cutoff. Those high energy particles create questions related to radiation belts and atmospheric neutrinos. To understand the origin of these particles, we use a trajectory

Anthropogenic Space Weather

, 2017
Anthropogenic effects on the space environment started in the late 19th century and reached their peak in the 1960s when high-altitude nuclear explosions were carried out by the USA and the Soviet Union.

Artificial perturbations of the radiation belts [PDF]

, 1972
A review is given of the properties of the radiation belts which have been produced by high-altitude nuclear detonations. The low-yield, Argus devices, 1, 2, and 3, and the Soviet test of 1 November 1962 injected intense electron fluxes in narrow L-shell
