Spatiotemporal profile of emission from oscillating dc micro discharges
T. Kuschel, N. Škoro, D. Marić +4
The axial light distributions in parallel-plate dc microdischarges in argon show similar behavior to large scale discharges. Between the low-current Townsend mode and the high curr…
Oscillation modes of dc microdischarges with parallel-plate geometry
Ilija Stefanović, Thomas Kuschel, Nikola Škoro +3
Two different oscillation modes in microdischarge with parallel-plate geometry has been observed: relaxation oscillations with frequency range between 1.23 and 2.1 kHz and free-run…
Spatial dynamics of helium metastables in sheath or bulk dominated rf micro-plasma jets
B Niermann, T Hemke, N Y Babaeva +4
Space resolved concentrations of helium He metastable atoms in an atmospheric pressure radio-frequency micro-plasma jet were measured using tunable diode laser absorption spectrosc…
Axial light emission and Ar metastable densities in a parallel plate dc micro discharge in steady state and transient regimes
T Kuschel, B Niermann, I Stefanović +5
Axial emission profiles in a parallel plate dc micro discharge (feedgas: argon; discharge gap d=1mm; pressure p=10Torr) were studied by means of time resolved imaging with a fast I…
