The Leibniz Institute for Plasma Science and Technology (INP) is the largest non-university institute in the field of low temperature plasmas, their basics and technical applications in Europe. The institute carries out research and development from idea to prototype. The topics focus on the needs of the market. At present, plasmas for materials and energy as well as for environment and health are the focus of interest.

The localised density of H₂O₂ in the effluent of a cold atmospheric pressure plasma jet determined by continuous-wave cavity ring-down spectroscopy

Plasma Chemical Processes

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. By performing Abel inversion on the Gaussian fits, spatial distributions of H2O2 in x and y and in x and z direction were obtained.

Plasma Diagnostics Properties

Diagnostics method: spatially resolved continuous wafe cavity ring-down spectroscopy (cw-CRDS) at a laser wavelength λ=1230 cm-1 (8.1 µm).
