The possible resonant acceleration of ions by a space-charge wave of a magnetized electron beam is analyzed for a system in which the motion of the ions and the wave are kept synchronized. The required variation in the wave phase velocity is produced by a special profile of the external magnetic field. The amplitude of the space-charge wave grows as the ions are accelerated by virtue of a two-stream instability. The ion motion has been simulated numerically to study the capture of the ions by the wave and the subsequent dynamics of the ion bunches. The electron motion is assumed to be linear. The numerical simulation is also used to study the effect of a nonlinearity of the electron motion, which drives a satellite instability of the accelerating wave. The beam parameters at which this acceleration mechanism can operate are given. The efficiency of this acceleration is evaluated.
