The single-particle approximation is used to analyze ion dynamics in the field of a slow cyclotron wave during ion transport and acceleration in the central cavity of cylindrical electron beams. A characteristic feature of the problem is that it is necessary to consider simultaneously axial and transverse ion oscillations having roughly equal frequencies in an accelerating field that varies over the beam cross section. It is shown that nonuniformity of the accelerating field results in incomplete trapping of a monoenergetic ion beam during transport, and it is necessary to modulate the phase velocity of the traveling wave in a complicated way during acceleration because of the high degree of ion bunching prior to acceleration. The ion capture coefficient during transport is calculated, together with the phase boundaries and velocity spread of the ion bunches. In the acceleration mode, the ion capture coefficient exceeds 50% even without ion bunching prior to acceleration. The maximum ion current which can be accepted and accelerated in an autoresonant accelerator is determined.
