Figure 4
(a, c) Recorded images of the front view (a) and side view (c) with a \(t_{\textrm{recording}}\) of 0.154 \(\mu\)s. (b, d) Floating probe voltage (\(V_{\textrm{float}}\)), voltage and current of the AIP (\(V_{\textrm{AIP}}\) and \(I_{\textrm{AIP}}\)), and recording voltage signal of the ultra-high-speed camera (\(V_{\textrm{recording}}\)) over time for front-view (b) and side-view (d) measurement. The color bar denotes the light intensity. All measurements were taken under the following conditions: P\(_{\textrm{RF}}\) of 40 W to maintain the background plasma, pressure of 166.4 mTorr, and argon injection of 50 sccm.
