Abstract : Steady-state and afterglow measurements of electron densities have been made in O2 - N2 mixtures weakly ionized by a spatially uniform flux of 1.5 Mev electrons from a Van de Graff accelerator. The plasma is contained in a large uhf resonant cavity to which mass and optical spectrometers are appended; electron densities are deduced from measured shifts in the resonant frequency of the cavity.
