Plasma diagnostics by cross-correlation spectroscopy in investigations of chemical analysis.it suitable for integrair at atmospheric pressure

An attempt has been made, to use the technique of spatially unresolved cross-correlation spectroscopy for the prognosis of chemical efficiency of negative corona of the type 'point-to-plane' in air. The experiments were carried out in an open gas flow system at atmospheric pressure. DC voltage was varied within the range 8.5-10.5 kV. Spatially unresolved intensities 1(t) for the spectral band of the 0-0 transition of the second positive system of nitrogen (λ = 337.1 nm) were recorded simultaneously with the measurements of ozone yield and electrical characteristics of the discharge.
