Cold plasma jets at atmospheric pressure have become the standard reactors used for treatment of various biosamples and other application. The object of this experimental study is one such reactor powered by a short-pulse voltage with a rise time ≈400 ns, operating with helium gas. The main aim of the investigation was to obtain the data on the jet streamer space–time development and plasma parameters near the target. Axial and radial structure was examined along with gas temperature and electric field above the target. Results show a comparably fast streamer progression (105 m/s) with strong electric field in the period of maximum current (33 kV/cm). These characteristic features can be attributed to the fast rise of the voltage pulse.
