Charged-particle energy balance for multiple scattering in a randomly inhomogeneous magnetic field
Abstract
An important problem of plasma astrophysics and cosmic-ray physics is the motion of charged particles in a random magnetic field. A theory is developed for energy exchange between high-energy charged particles and random magnetic-field inhomogeneities frozen into a moving plasma. The transport equation is used to obtain equations for the energy density of charged particles and expressions for the energy flux density and the particle energy source. It is shown that variations of particle energy are determined by a particular form of the particle distribution function. The formation of charged-particle energy spectra in the case of multiple scattering by random magnetic-field inhomogeneities is considered.
