Аннотация

We report on the results of spectroscopic measurements of electron concentration Ne and temperature Te, as well as the reduced electric field strength E/N in the plasma of a high-voltage nanosecond discharge in the gap with a strongly nonuniform electric field distribution, which is filled with nitrogen under the atmospheric pressure. The possibility of using the method for determining Te and E/N, which is based on the determination of the ratio of the peak intensities of the ionic N2 + (λ = 391.4 nm) and molecular N2 (λ = 394 nm) nitrogen bands, is proved. We detected the mean values of quantities Ne, Te, and E/N amounting to ∼2 × 1014 cm-3, ∼2 eV, and ∼240 Td, respectively. In addition, the dynamics of these quantities is determined.
