  2. Modeling the formation of current sheets in symmetric and asymmetric reconnection

    … phase space distribution function based on adiabatic invariants. We then apply this two model problems-Fermi acceleration and electron trapping-to extend previous results in these areas and model their effects on parallel heating. Following this, we run a battery of simulations of …

  3. Development and Application of Stochastic Methods for Radiation Belt Simulations

    … electron phase space density as a function of adiabatic invariants M, K and L. Based on this theory, a three-dimensional radiation belt electron model in adiabatic invariant coordinates, named REM (for Radbelt Electron Model), is constructed and validated against both known results from other …

  4. Modelling the Exposure of Satellites in Medium Earth Orbit to Proton Belt Radiation

    … density in terms of the first, second and third adiabatic invariants μ, K and L. This chapter demonstrates how key processes can be quantified, including transport via radial diffusion, the cosmic ray albedo neutron decay source and coulomb collisional loss. In Chapter 4, a 2D version of the …

  5. A statistical study of plasmawaves and energetic particles in the outer magnetosphere

    … are often described in terms of three kinds of adiabatic invariants. Energetic electrons are often unstable to the whistler-mode chorus waves, and ions, to the electromagnetic ion cyclotron (EMIC) instability. These waves play an important role in the dynamics of the magnetosphere by energizing …
