We introduce a 3D hybrid model for streamer discharges that follows the dynamics of single
electrons in the region with strong field enhancement at the streamer tip while approximating
the many electrons in the streamer interior as densities. We explain the method and present
first results for negative streamers in nitrogen. We focus on the high electron energies
observed in the simulation.
