Ion composition in a nitrogen discharge plasma
Abstract
The ion composition in the plasma of a positive column from a glow-discharge (with cold molybdenum electrodes) in molecular nitrogen is studied by mass-spectrometric analysis. The electron concentration, electric field intensity, and the electron energy distribution function are determined with the aid of probes at nitrogen pressures ranging from 0.1 to 1.0 mm Hg and discharge currents from 10 to 60 mA. N+, N2+, N3+, and N4+ ions were observed within the entire range of test parameters. The relative content of each ion type is determined as a function of the plasma parameters. Possible ion production processes are examined.
