Simulation of convoy-electron emission

Abstract

We present a microscopic simulation of convoy-electron production and transport through solids. Using a classical transport theory, we calculate the forward-ejected electron spectrum for 3-MeV/u ${\mathrm{H}}^{0}$ projectiles traversing carbon foils of different thicknesses. We find excellent agreement with experiment in both shape and absolute magnitude of the convoy-electron spectrum over a wide range of electron energies and foil thicknesses. Our study provides detailed information on the relative importance of competing pathways contributing to convoy-electron emission.
