Diagram of the experimental apparatus and the diagnostics used for studying this APPJ source.
(a) Unfiltered image sequence of the plasma jet and CDBD emission acquired with a gated ICCD camera. The frames are at intervals from the onset of emission. (b) emission profiles acquired with the plasma jet and CDBD PMT detectors and the total current, all averaged over 500 pulses. The data was acquired using a 5% gas mixture flowing at with an voltage pulse at a repetition rate.
Image sequences acquired with an ICCD camera under the same conditions as Fig. 2. The images show emission through bandpass filters centered at (a) 390 and (b) .
Variation in arrival delay of the plasma jet emission with PMT detector position, measured with respect to the peak of the displacement current for the same operating conditions as Fig. 2 through a bandpass filter centered at . The propagation speed derived from the linear fit is .
Operating conditions for our dielectric capillary configuration. Conditions used for acquiring the data shown in Figs. 2–4 are listed in parentheses.
