Focused acceleration of cosmic-ray particles in non-uniform magnetic fields
(The American Astronomical Society, 2011)The Fokker–Planck equation for cosmic-ray particles in a spatially varying guide magnetic field in a turbulent plasma is analyzed. An expression is derived for the mean rate of change of particle momentum, caused by the ... -
The telegraph approximation for focused cosmic-ray transport in the presence of boundaries
(IOP Sciences, 2015)Diffusive cosmic-ray transport in nonuniform large-scale magnetic fields in the presence of boundaries is considered. Reflecting and absorbing boundary conditions are derived for a modified telegraph equation with a ... -
The telegraph equation for cosmic-ray transport with weak adiabatic focusing
(EDP SCIENCES S A, 2013)Time-dependent solutions of a spatial diffusion equation are often used to describe the transport of solar energetic particles, accelerated in large solar flares. Approximate analytical solutions of the diffusion approximation ...
