Spatial distribution of fluorescent light emitted from neon and nitrogen excited by low energy electron beams

The spatial distributions of the intensity of fluorescent light emitted from neon and nitrogen excited with 12 keV electron beams at gas pressures from 250 to 1400 hPa are measured. The CASINO program, which performs Monte Carlo simulations of electron scattering, has offered a simple and relatively precise method to predict the spatial distribution of the light emitting species created by low energy electron beams in dense gas.
