Abstract

Reactive atomic species play a key role in emerging cold atmospheric pressure plasma applications, in particular, in plasma medicine. Absolute densities of atomic oxygen and atomic nitrogen were measured in a radio-frequency driven non-equilibrium plasma operated at atmospheric pressure using vacuum ultra-violet (VUV) absorption spectroscopy. The experiment was conducted on the DESIRS synchrotron beamline using a unique VUV Fourier-transform spectrometer. Measurements were carried out in plasmas operated in helium with air-like N2=O2 (4:1) admixtures. A maximum in the O-atom concentration of (9.1±0:7)10^20 m3 was found at admixtures of 0.35 vol. %, while the N-atom concentration exhibits a maximum of (5.7±0.4)10^19 m3 at 0.1 vol. %.
