Abstract

Atmospheric-pressure plasma jet provides an effective mode for many potential applications. Unipolar repetitive pulses of 25-ns rise time and 40-ns duration are used to drive a single electrode plasma jet in open air. He, Ar, N₂, and air are chosen as the feed gases. Kinds of images of the observed plasma jets are presented under different experimental conditions. The diffusive appearances with N₂ or air flow are different from the needle-like mode with He or Ar flow.
