O density

Spatially resolved absolute densities of atomic oxygen obtained experimentally for N = 4 as a function of the peak-to-peak value of the driving voltage waveform.

(b) Peak and (c) mean atomic oxygen densities as a function of the peak-to-peak value of the applied voltage waveform for different N. The data are measured at positions y = 0.5 mm and z = -15 mm.

Space and time averaged values of the atomic oxygen density obtained experimentally for different numbers of driving harmonics, N, and molecular oxygen admixtures for “peaks”-voltage waveforms at fix

(a)-(c) Measured spatially resolved absolute densities of atomic oxygen obtained for different oxygen admixture concentrations.

(a)-(c) 2D spatial distribution of the atomic oxygen density inside the jet obtained from the numerical solution of equation (8) for different numbers of consecutive harmonics, N.

(a) Spatially resolved absolute densities of atomic oxygen obtained experimentally and computed from the numerical solution of eq. (8).

Measured 2D space resolved absolute density of atomic oxygen between the electrodes (x-direction) and the quartz walls (y-direction).
