usesConfiguration

• Configuration for COST-Jet: sinusoidal waveform of 13.56 MHz with a peak-to-peak voltage of 850 V 
• Configuration for coordinate system: The symmetry axis of the plasma effluent is defined as the z-axis, normalised to the tip of the respective jet’s nozzle, such that the effluent exits the source at z = 0 
• Configuration for cw-CRDS: Optical cavity composed of two highly reflective mirrors (reflectivity 99.98%, radius of curvature 100 cm), separated by a distance of 54.5 cm; cavity length continuously modulated by 4 μm; quantum cascade laser with a tuning range of 1224 - 1234 cm−1; absorption feature probed within the spectral range of 1231.57 - 1232.00 cm−1 
• Configuration for gas medium: Humidified helium containing (3300 +- 100) ppm water at a flow rate of 1 slm at atmospheric pressure 
• Configuration for kINPen-sci: sinusoidal waveform of 860 kHz with a peak-to-peak voltage of 3kV 
• The kINPen-sci was operated at a sinusoidal waveform of 860 kHz with a peak-to-peak voltage of 3kV. The COST-Jet was operated at a sinusoidal waveform of 13.56 MHz with a peak-to-peak voltage of 850 V.
