Title: Afterglow Studies in Noble-Gas-Hydrogen Mixtures
Abstract:The time dependence of the electron density during the afterglow period of plasma produced in helium-hydrogen, neon-hydrogen, and argon-hydrogen mixtures was measured by means of the microwave cavity ...The time dependence of the electron density during the afterglow period of plasma produced in helium-hydrogen, neon-hydrogen, and argon-hydrogen mixtures was measured by means of the microwave cavity method. The time dependence was found to be exponential during the later part of the afterglow period for pressures up to about 25 Torr. The relevant time constant depended on the plasma excitation condition at all values of pressure in helium-hydrogen mixtures, while this dependence was not observed in neon-hydrogen mixtures at pressure above 12 Torr and was absent in argon-hydrogen mixtures. The ion mobility values calculated from the measured ambipolar diffusion coefficients are 38±4 cm2/V·sec for helium-hydrogen, 17±1.0 cm2/V·sec for neon-hydrogen and 6.3±0.5 cm2/V·sec for argon-hydrogen mixtures.Read More
