A model for the acceleration and transport of suprathermal ions associated with interplanetary coronal mass ejections (CMEs) is presented. The combined mechanisms of stochastic acceleration in the turbulence near interplanetary shocks, first-order Fermi acceleration, stationary spatial diffusion in field irregularities of magnetic clouds, and time-dependent propagation in the upstream solar wind are described. Ions from the bulk solar wind are considered as source populations of suprathermal
