Abstract :
The Boltzmann equation for a population of relativistic electrons in a constant external electric field in air is solved numerically in order to determine parameters of the resulting runaway electron beam. The numerical solution takes advantage of algorithms from computational fluid dynamics. The work revises the results from the original work where the numerical solution was found to be unstable
