Abstract
There is increasing evidence to suggest that energetic particles
observed in ``gradual'' solar energetic particle (SEP) events are
accelerated at shock waves driven out of the corona by coronal mass
ejections (CMEs). Energetic particle abundances suggest too that SEPs
are accelerated from in situ solar wind plasma rather than from high
temperature material. We present here a a dynamical time dependent model
of particle acceleration at a propagating interplanetary shock. The
model includes the determination of the particles injection energy, the
maximum energy of particles accelerated at the shock, energetic particle
spectra at all spatial and temporal locations, and the dynamical
distribution of particles that are trapped in the post shock flow and
those that escape upstream and downstream from the evolving shock
complex. .
