On the threshold energization of radiation belt electrons by double layers
Using a Hamiltonian approach, we quantify the energization threshold of electrons interacting with radiation belts’ double layers discovered by Mozer et al. (2013). We find that double layers with electric field amplitude E0 ranging between 10 and 100 mV/m and spatial scales of the order of few Debye lengths are very efficient in energizing electrons with initial velocities v∥ ≤ vth to 1 keV le...
متن کاملEnhanced radial transport and energization of radiation belt electrons due to drift orbit bifurcations
[1]Relativistic electron intensities in Earth's outer radiation belt can vary by multiple orders of magnitude on the time scales ranging from minutes to days. One fundamental process contributing to dynamic variability of radiation belt intensities is the radial transport of relativistic electrons across their drift shells. In this paper we analyze the properties of three-dimensional radial tra...
متن کاملAtmospheric losses of radiation belt electrons
[1] 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. It is constrained by high-altitude ( 20,000 km) satellite measurements of the energy spectra and pitch angle distribut...
متن کاملUltra-low-frequency wave-driven diffusion of radiation belt relativistic electrons
Van Allen radiation belts are typically two zones of energetic particles encircling the Earth separated by the slot region. How the outer radiation belt electrons are accelerated to relativistic energies remains an unanswered question. Recent studies have presented compelling evidence for the local acceleration by very-low-frequency (VLF) chorus waves. However, there has been a competing theory...
متن کاملEffects of ULF wave power on relativistic radiation belt electrons: 8–9 October 2012 geomagnetic storm
Electromagnetic ultralow-frequency (ULF) waves are known to play a substantial role in radial transport, acceleration, and loss of relativistic particles trapped in the Earth’s outer radiation belt. Using in situ observations by multiple spacecraft operating in the vicinity of outer radiation belts, we analyze the temporal and spatial behavior of ULF waves throughout the geomagnetic storm of 8–...
