Relativistic electron scattering by electrostatic upper hybrid waves in the radiation belt

Upper limit on the inner radiation belt MeV electron intensity

No instruments in the inner radiation belt are immune from the unforgiving penetration of the highly energetic protons (tens of MeV to GeV). The inner belt proton flux level, however, is relatively stable; thus, for any given instrument, the proton contamination often leads to a certain background noise. Measurements from the Relativistic Electron and Proton Telescope integrated little experime...

Ultra-relativistic electrostatic Bernstein waves

A new general form of the dispersion relation for electrostatic Bernstein waves in ultra-relativistic pair plasmas, characterized by a−1 = kBT/(mec) 1, is derived in this paper. The parameter Sp = a 0/ωp, where 0 is the rest cyclotron frequency for electrons or positrons and ωp is the electron (or positron) plasma frequency, plays a crucial role in characterizing these waves. In particular, Sp ...

Electron Lifetimes in the Outer Radiation Belt

3 Data assimilation aims to smoothly blend incomplete and inaccurate ob-4 servational data with dynamical information from a physical model, and be-5 come an increasingly important tool in understanding and predicting me-6 teorological, oceanographic and climate processes. As space-borne observa-7 tions become more plentiful and space-physics models more sophisticated, 8 dynamical processes in ...

Optimal Estimation of Relativistic Electron Lifetimes in the Outer Radiation Belt

Theoretical and numerical analysis of radiation belt electron precipitation by coherent whistler mode waves

The interaction between coherent whistler mode waves and energetic radiation belt electrons can result in pitch angle scattering of electrons into the bounce loss cone and subsequent precipitation. In studying the effects of VLF transmitter signals on particle precipitation, past modeling efforts have focused on the computation of diffusion coefficients for a Fokker-Planck model. In contrast, t...
