Scientific paper

The rapid acceleration of ions by a large-amplitude magnetosonic wave is discussed. Theory and relativistic particle simulation show that a large-amplitude magnetosonic wave (such as a shock wave) can trap some fraction of ions and resonantly accelerate them in the direction perpendicular to the ambient magnetic field. In a rather strong magnetic field, those resonant ions gain relativistic energies (above 1 GeV) in a short time period (much shorter than 1 s). The condition for the ion trapping is also studied; a few percent of ions can be strongly accelerated, and more than 10 percent of ions can be mildly accelerated for the shock with the Alfven Mach number of about 2.
