| Abstract |
Charged particles can be accelerated efficiently in a presence of spatially correlated magnetohydrodynamic (MHD) waves by successive mirror reflection (Fermi process). In order to construct a statisti...cal model of this process, we study interaction between an MHD pulse and a charged particle, both numerically and analytically. When the particle velocity is small (adiabatic regime), the probability that the particle be reflected by the MHD pulse is essentially determined by the pitch angle only, and is thus independent of the velocity. On the other hand, in the non-adiabatic regime, the reflection probability is shown to be inversely proportional to the square root of the normalized velocity. We discuss our numerical as well as analytical results of the interaction process with various pulse amplitude, pulse shape, and the pulse winding number.show more
