“…Immediately after the breakdown, the bifurcation diagram resembles a scatter plot indicating chaotic oscillation, and this behavior continues until 3.54 V, when the discharge becomes periodic with period 2P. As input voltage is increased further, the discharge remains in a 2P state until 4.92 V, at which point the diagram appears to diverge into a set of closely scattered points, indicating the phase space reconstruction is that of a torus, suggesting quasi- Many studies of DBDs have highlighted the importance of space charge accumulation in maintaining a stable discharge [29,38]. In theory, during each voltage half cycle, plasma forms resulting in surface charge accumulation on the surrounding dielectric surfaces, perturbing the applied field and causing the plasma to extinguish.…”

Abstract:We report detailed characterization of a low-temperature atmosphericpressure plasma jet that exhibits regimes of periodic, quasi-periodic and chaotic behaviors. Power spectra, phase portraits, stroboscopic section and bifurcation diagram of the discharge current combine to comprehensively demonstrate the existence of chaos, and this evidence is strengthened with a nonlinear dynamics analysis using two control parameters that maps out periodic, period-multiplication, and chaotic regimes over a wide range of the input voltage and gas flow rate. In addition, optical emission signatures of excited plasma species are used as the second and independent observable to demonstrate the presence of chaos and period-doubling in both the concentrations and composition of plasma species, suggesting a similar array of periodic, quasi-periodic and chaotic regimes in plasma chemistry. The presence of quasi-periodic and chaotic regimes in structurally unbounded low-temperature atmospheric plasmas not only is important as a fundamental scientific topic but also has interesting implications for their numerous applications. Chaos may be undesirable for industrial applications where cycle-tocycle reproducibility is important, yet for treatment of cell-containing materials including living tissues it may offer a novel route to combat some of the major challenges in medicine such as drug resistance. Chaos in low-temperature atmospheric plasmas and its effective control are likely to open up new vistas for medical technologies.2

“…For a sinusoidal applied voltage, the important role of surface charges deposited during previous voltage periods on the uniformity of the discharge obtained in a plane-plane dielectric barrier discharge configuration was pointed out by Massines et al [11,12]. In Opaits et al [13], the influence of the constant bias voltage on the value of the deposited surface charge by successive voltage pulses of a surface dielectric barrier discharge has been shown.…”

To cite this version:J. Jánský, A. Bourdon. Surface charge deposition inside a capillary glass tube by an atmospheric pressure discharge in air. European Physical Journal: Applied Physics, EDP Sciences, 2011, 55 (1) Abstract. This paper presents simulations of the dynamics of surface charging by an air plasma discharge at atmospheric pressure initiated by a needle anode inside a capillary glass tube. During the discharge propagation in the tube, the highest positive surface charge density is observed close to the point electrode.We have shown that during the discharge propagation, the positive surface charge is increasing behind the discharge front, while the electric field at the surface is decreasing. Then, we have studied the influence of the tube radius, its permittivity and the applied pulsed voltage on surface charges. We have shown that the surface charge density during the discharge propagation is inversely proportional to the tube radius and surface charge densities of 30 − 50 nC/cm 2 for a tube with R tube = 100 µm and an applied voltage of 12 kV/cm have been obtained. We have also noted that a higher permittivity results in a higher surface charge density and a faster surface charge deposition. Then we have shown that the surface charge deposited is proportional to the applied voltage. Finally, at the end of the voltage pulse, our simulations indicate that the positive surface charge deposited during the discharge propagation in the tube decreases to very low values in few nanoseconds.

“…7,8 The chemical reaction set used in the model is composed from publications on discharge modeling found in literature 1,9-11 and consists of 18 chemical reactions which are shown in Table I and an extra electron energy loss term for the production of radiative species. 12 The experimental setup under consideration is very similar to the setup used by Massines et al 13 and Mangolini et al 1 for the sake of comparison with experiment. The configuration consists of two parallel electrodes both covered with alumina dielectrics ͑⑀ r =9͒ of 1 mm thickness.…”

We present in this letter how a molecular gas such as nitrogen at different levels of impurity dominates the ionic composition of an atmospheric pressure noble gas plasma such as in helium. The positive charge in the discharge is only determined by helium ions if the discharge gas contains less than 1ppm of impurity. Above this impurity level, the positive charge is completely determined by the impurity nitrogen. The higher the relative nitrogen concentration, the more N4+ dominates over N2+. If the impurity level is between 1 and about 20ppm, N2+ is clearly the most abundant positive ion but for higher levels of impurity, N4+ almost completely determines the positive charge.
