abstract: 'We have recently presented a numerical model to simulate the acceleration
  and transport of energetic particles at coronal shock waves, which includes the
  back-reaction of the energetic particles on the Alfv\''en waves responsible for
  their scattering in the ambient medium [Vainio, R., Laitinen, T., 2007. Monte Carlo
  simulations of coronal diffusive shock acceleration in self-generated turbulence.
  Astrophysical Journal 658, 622-630]. The model results imply that the acceleration
  of energetic protons to energies exceeding 100 MeV can occur in some minutes in
  parallel coronal shocks driven by fast CMEs. In this paper we give a detailed description
  of the numerical model and its foreseen extensions. We extend the parameter study
  presented in the first paper to cover (shorter and) longer time scales, and present
  the intensities observed in the interplanetary medium during the initial phases
  of an SEP event. We also study the scattering mean free path resulting from the
  self-consistent computations. Finally, the potential of the model to explain ion
  acceleration up to relativistic energies is discussed.'
