Electron Energy Deposition in Atomic Nitrogen

Abstract

A discrete, time-dependent energy deposition model is used to study high-energy electron-beam (100 eV to 10 MeV) deposition in atomic nitrogen. Both time-dependent and steady-state secondary electron distributions are computed. The loss function, mean energies per electron-ion air production (DELTA W), production efficiencies, and yield functions are presented for a wide range of energies.The latest experimental and theoretical cross section are used in the model which predicts DELTA W is approximately 31 eV for a wide range of beam energies and background ionization fractions.
