The localised density of H₂O₂ in the effluent of a cold atmospheric pressure plasma jet determined by continuous-wave cavity ring-down spectroscopy
The data set comprises full cavity ring-down spectra and absorption coefficients obtained from on/off-resonance measurements, in order to determine the spatial distribution of H2O2 in the cold atmospheric pressure plasma jet kINPen-sci. Therefore, the plasma jet was operated with 3 slm Ar and 3000 ppm water, and was equipped with a gas curtain of 5 slm O2. To determine the effective absorption length, the H2O2 absorption was measured in radial direction. These radial fits had a Gaussian-like shape.
