Abstract
Motion of charged particles in arbitrary random electric and magnetic fields is analyzed, and the statistical acceleration rate is derived in terms of power spectra of functions of the applied fields. The treatment is extended to stochastic acceleration in a magnetic mirror; upper and lower bounds (differing by a factor of 2) for the particle acceleration rate are derived for the case when the half-power spectrum of the electric field spans the spectrum of particle gyrofrequencies in the mirror.Keywords
