To use a 3D numerical MHD experiment representing magnetic flux emerging intoan open field region as a background field for tracing charged particles. Theinteraction between the two flux systems generates a localised current sheetwhere MHD reconnection takes place. We investigate how efficiently thereconnection region accelerates charged particles and what kind of energydistribution they acquire. The particle tracing is done numerically using theGuiding Center Approximation on individual data sets from the numerical MHDexperiment. We derive particle and implied photon distribution functions havingpower law forms, and look at the impact patterns of particles hitting thephotosphere. We find that particles reach energies far in excess of those seenin observations of solar flares. However the structure of the impact region inthe photosphere gives a good representation of the topological structure of themagnetic field.
