Abstract

We present images and basic characteristics and
describe transition mechanisms between three dc discharges in
atmospheric air point-to-plane or point-to-water gap. With increasing
applied voltage, a streamer corona transits to a transient
spark: a repetitive spark with very short (∼100-ns) current pulses
(∼1 A) of very limited energy. With an appropriate ballast resistor,
this transient regime evolves into a pulseless glow discharge.
These three discharges generate nonequilibrium plasmas of high
chemical activity interesting for environmental and biomedical
applications.
