Abstract

An atmospheric-pressure argon plasma jet is initiated by the barrier discharge in a capillary, through which argon was flown. The spectral composition of radiation emitted by the jet in the atmosphere and its variation in the space are analyzed in detail. The jet radiation spectrum is shown to be predominantly formed by spectral transitions of argon and oxygen atoms, by electron-vibrational transitions of the first positive system of nitrogen molecules N2(C3Πu→B3Πg), and by transitions of hydroxyl radical OH(A2Σ+→X2Π).
