Dielectric barrier discharge source for supersonic beams

Review of Scientific Instruments, 2009
We 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.

Applications of dielectric barrier discharges

12th International Conference on High-Power Particle Beams. BEAMS'98. Proceedings (Cat. No.98EX103), 2002
Dielectric 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 ...

Optical Characterization of Surface Dielectric Barrier Discharges

IEEE Transactions on Plasma Science, 2011
Surface 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.

Peculiarities of Dielectric Barrier Discharges

Contributions to Plasma Physics, 2001
The 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

The influence of barrier on dielectric barrier discharge

SPIE Proceedings, 2011
A new method is presented for measuring the electric parameters in dielectric barrier discharge (DBD), and the effect of barrier on discharge is investigated. Results show that the number of discharge current is variable in different half period of applied voltage, and the current pulse width is in the range of 160 to 280ns.

Nanosecond-Pulsed Uniform Dielectric-Barrier Discharge

IEEE Transactions on Plasma Science, 2008
The authors report a new nanosecond-pulsed dielectric-barrier discharge (DBD) for sterilization and other medical applications. In the literature, several discharges have been reported, with pulse durations on the order of hundreds of nanoseconds. In this paper, a novel pulsed DBD has been developed, with only few tens of nanosecond pulsewidths working

Modeling of micro-dielectric barrier discharges

2010 Abstracts IEEE International Conference on Plasma Science, 2010
Summary form only given. Arrays of micro-plasmas having dimensions of tens to hundreds of microns are finding use as sources of radicals and charged particles in addition to their conventional use as photon sources. In one variant of these devices, the electrodes are fully or partially covered by dielectrics, and so they operate as dielectric barrier ...

Electrodynamic force of dielectric barrier discharge

Journal of Applied Physics, 2011
The periodic electrostatic force of dielectric barrier discharge (DBD) in nitrogen for flow control is investigated by a system of physics-based, two-dimensional model equations. The plasma generation process of DBD is mainly the avalanche growth of electrons through the secondary emission from cathode.

Space charge effects in a dielectric barrier discharge barrier discharge plasma

The 30th International Conference on Plasma Science, 2003. ICOPS 2003. IEEE Conference Record - Abstracts., 2003
Summary form only given, as follows. Dielectric barrier discharge (DBD) is the one of well-known discharge types at the atmosphere pressure. The characteristic of this discharge can be expressed in terms of a randomly distributed microdischarge, which is heterogeneously formed cylindrical current filament in a discharge space.

Modeling of ac dielectric barrier discharge

Journal of Applied Physics, 2010
The qualitative electrodynamic field of the dielectric barrier discharge in air is studied by a three-component, drift-diffusion plasma model including the Poisson equation of plasmadynamics. The critical media interface boundary conditions independent of the detailed mechanisms of surface absorption, diffusion, recombination, and charge accumulation ...
