Square superlattice pattern in dielectric barrier discharge
Physical Review E, 2006We report the observation of a square superlattice pattern in a dielectric barrier discharge system. The correlation measurements indicate that the square superlattice pattern is an interleaving of two different transient square sublattices. The interplay between the charge pattern and the discharge filament pattern is discussed.

Honeycomb hexagon pattern in dielectric barrier discharge
Physical Review E, 2007We report on a honeycomb hexagon pattern in dielectric barrier discharge. It bifurcates from a square pattern as the applied voltage is increased. A phase diagram of the pattern types as a function of the gas component and applied voltage is presented.

Applications of dielectric barrier discharges
12th International Conference on High-Power Particle Beams. BEAMS'98. Proceedings (Cat. No.98EX103), 2002Dielectric barrier discharges (DBDs) in oxygen and air are well established for the production of large quantities of ozone and are more recently being applied to a wider range of plasmachemical processes. As an introduction of this type of gas discharge, the main plasmaphysical features of sinusoidal-driven DBDs (transient, non-thermal plasmas at ...

Hexagonal superlattice state in dielectric barrier discharge
Physical Review E, 2006We report on the observation of a hexagonal superlattice state (HSS) in dielectric barrier discharge in air/argon near atmospheric pressure. It bifurcates directly from the hexagonal state by increasing the applied voltage. The correlation measurements indicate that the HSS is an interleaving of three different transient sublattices.

Numerical simulation of surface dielectric barrier discharge
2016 IEEE International Conference on Information and Automation (ICIA), 2016In order to better study and reveal the discharge mechanism and evolution of the dielectric barrier plasma generator, in this paper, the discharge in atmospheric argon is simulated by 2D numerical method. From the discharge particle chemical reaction of Ar and Ars electronic, it can be obtained that the relationship between the particle concentration ...

Dielectric Barrier Discharge Ionization of Perfluorinated Compounds
Analytical Chemistry, 2015The soft ionization ability based on plasma-jet protonation of molecules initiated by a dielectric barrier discharge ionization source (DBDI) is certainly an interesting application for analytical chemistry. Since the change of an applied sinusoidal voltage may lead to different discharge modes the applied discharge was powered by a square wave ...

Optical Characterization of Surface Dielectric Barrier Discharges
IEEE Transactions on Plasma Science, 2011Surface dielectric barrier discharges (SDBDs) provide homogeneous plasma over a large surface area. This allows surface treatments of foils, textiles, or fibers. In this paper, we present results of a study to characterize the pulsed performance of SDBD by fast imaging of the plasma development.

Dielectric barrier discharge source for supersonic beams
Review of Scientific Instruments, 2009We present a new excitation source for pulsed supersonic beams. The excitation is based on dielectric barrier discharge in the beam. It produces cold beams of metastable atoms, dissociated neutral atoms from molecular precursors, and both positive and negative ions with high efficiency and reliability.

Liquid analysis dielectric capillary barrier discharge
Analytical and Bioanalytical Chemistry, 2010In this study a simple micro-tube-based system for analysis of metal-containing liquids is introduced and its analytical performance is evaluated. It is based on a miniaturised dielectric barrier discharge driven at atmospheric pressure. The emission lines of various elements are observed.

Peculiarities of Dielectric Barrier Discharges
Contributions to Plasma Physics, 2001The dielectric barrier discharge (DBD) is a highly transient, non-thermal discharge form, which exists in a broad pressure range. It occurs in arrangements, where a dielectric layer covers at least one electrode. The dielectric quenches the current and distributes the discharge over the whole surface. Depending on the geometrical conditions three basic
