(a) time evolution at two different values of and at two contents. Pulse duration is , period is . rms error in saturation (at 1600 W) ≈80 K. (b) Rotational spectra (FPS of ) taken at three different delay times after the beginning of the plasma pulse. was determined using the P1/P2 peaks ratio by the empirical expression from Ref. 15 (, 15% of ).
(a) time evolution at different pulse durations and at the constant time averaged power. Period is . (b) time evolution at different pulse durations and at . Duty .
Time evolution of the of at two different values of the content. Pulse duration is , period is . . rms error in saturation is about 300 K.
The normalized intensities of the Ar (750.4nm), (380.5nm), (391.5nm), and N (821.6 nm) emission lines during the plasma pulse. Pulse duration is , period is . .
Gas temperature growth rate (TGR) at the beginning of a plasma pulse as a function of power . Inset: effective power ratio calculated based on the measured TGR and known gas heat capacity (21 J/mol/K).
