Abstract

The drift velocity of secondary electrons in electron-beam irradiated Ar/HCl gas mixtures was obtained by measuring both the current and electron densities as a function of an externally applied electric field. The measurements were performed for a variety of HCl concentrations between 0.1% and 5.0% and electric-field strengths between 0.1 and 10 Td (1 Td=10 ^-17 V cm²). The electron-beam pulse was 350 ns long, at an energy of 150 keV and current density between 4.2 and 0.017 A/cm². The electron density was measured by time-resolved infrared interferometry at 9.6 μm. The results show that the Ar/HCl system exhibits negative differential conductivity.
