The possibility of supplementary acceleration of charged particles in a moving magnetized plasma
Abstract
An equation in a diffusion approximation is derived in order to describe the propagation of fast charged particles in a moving plasma, taking into account the acceleration processes. The equation was obtained specifically from a Boltzmann kinetic equation including a collision term. It is shown that supplementary acceleration of the charged particles may occur if the plasma regular motion in the background plasma is caused by scattering from two different sources: magnetic field fluctuations (inhomogeneities); or a set of magnetic 'clouds' (shock waves, MHD discontinuities, plasma flows, and ejections). The efficiency of the supplementary acceleration process in various astrophysical media, including the sun, colliding galaxies, and interstellar space, is evaluated. The possibility of observing supplementary particle acceleration in laboratory plasmas is considered.
