Room-temperature atmospheric argon plasma jet sustained with submicrosecond high-voltage pulses
journal contribution
posted on 2009-08-21, 08:54 authored by James L. Walsh, Michael G. KongIn this letter, an experimental study is presented to characterize a room-temperature plasma jet in
atmospheric argon generated with submicrosecond voltage pulses at 4 kHz. Distinct from
sinusoidally produced argon discharges that are prone to thermal runaway instabilities, the pulsed
atmospheric argon plasma jet is stable and cold with an electron density 3.9 times greater than that
in a comparable sinusoidal jet. Its optical emission is also much stronger. Electrical measurement
suggests that the discharge event is preceded with a prebreakdown phase and its plasma stability
is facilitated by the short voltage pulses.
