The micro-discharge was repetitively produced using amplitude-modulated ac high voltage waveforms applied to the coplanar electrode geometry in a reactor, fed either with high-purity Ar or N2 at atmospheric pressure. The driving high-voltage amplitude was set to initiate just one single micro-discharge per one ac half-cycle. Images recorded within the two successive ac cycles provided evidence that the track left by the first micro-discharge influenced the propagation trajectory of consecutive streamers. Images of individual micro-discharges allowed evaluation of the luminous streamer channel diameter and its evolution along the streamer's propagation trajectory. Minimum luminous streamer channel diameters of 30 ± 6 µm and 50 ± 10 µm were fixed in Ar and N2, respectively.
