Experiments in which a 150 keV electron-beam pulse is injected into test gas mixtures at atmospheric pressure are described. Electron attaching gases, including O2, CO2, CH4 and SF6, are mixed with non-attaching base gases, N2 and Ar. The ionizing electron- beam current (1–100 A/cm2) provides a volume discharge between two electrodes. The discharge is used to determine the temporal behavior of gas resistivity as a function of beam current. Theoretical results for O2:N2 mixtures agree with experimental values. |
