Detection of hydrogen radicals in a dielectric barrier discharge by laser-induced fluorescence
Original language description
Absolute atomic hydrogen densities were measured by two-photon absorption laser-induced fluorescence (TALIF) in a volume dielectric barrier discharge, which was ignited in a mixture of argon and hydrogen in a plasma reactor at atmospheric pressure. Hydrogen atoms were excited by laser radiation with the wavelength 205 nm. We identified the main fluorescence parameters, e.g. the degree of saturation, the spectral profile of the absorption line and the dependency of the signal on the discharge phase. Thecalibration was done using TALIF of krypton with the 204 nm wavelength. The absolute concentrations of atomic hydrogen were determined based on different parameters of the system, e.g. the flow rate of the studied gases and the generator voltage.
