From: In vitro renal calculi destruction by a high-frequency glow discharge plasma
The voltage (A) and current (C) flowing through the electrode near the plasma discharge ignition threshold are shown. The characteristic time of enveloping the electrode with plasma is approximately 20 ms (half of the current band). Time-integrated image of a tungsten electrode with a diameter of 500 µm over a period of 20 ms: no plasma (B) and plasma on the electrode (D).
