“…Discharge optical emission spectrum was obtained using a fiberoptic bundle (Princeton Instruments-Acton, 10 fibers – 200 µm core) connected to the spectrometer (Princeton Instruments – Acton Research, Tri0Vista TR555 spectrometer system with PIMAX digital ICCD camera, Trenton, NJ) calibrated using Hg (Ar) spectral calibration lamp, Newport, and 63978 NIST Traceable Quartz Tungsten Halogen Calibrated Source, Newport. Electric field measurements were performed based on the method described by Starikovskaya et al [18, 19]. Briefly, ratio of emission from 0–0 vibrational transitions of the second positive (337.1 nm) system of molecular nitrogen and of the first negative (391.4 nm) system of molecular nitrogen ions was measured and electric field value was calculated using the technique described in [18, 19].…”

In this study, we report experimental results on fast ICCD imaging of development of nanosecond-pulsed dielectric barrier discharge (DBD) in atmospheric air and spectroscopic measurements of electric field in the discharge. Uniformity of the discharge images obtained with nanosecond exposure times were analyzed using chi-square test. The results indicate that DBD uniformity strongly depends on applied (global) electric field in the discharge gap, and is a threshold phenomenon. We show that in the case of strong overvoltage on the discharge gap (provided by fast rise times), there is transition from filamentary to uniform DBD mode which correlates to the corresponding decrease of maximum local electric field in the discharge.

“…Electric fields were measured by Starikovskaia et al [17] by time-resolved spectroscopy of emission from N 2 in nanosecond surface discharges sustained in air at pressures of 200 Torr to 1 atm. Voltage pulses were 25 ns in duration and 20 kV amplitude.…”

In atmospheric pressure discharges, ion energies are typically thought to be thermal with values dominantly <1 eV. In the heads of filaments in dielectric barrier discharges (DBDs), electric fields can exceed 200 kV cm −1 when the filament is far from a surface. As the filament approaches and intersects a dielectric surface, much of the applied potential is compressed into the voltage drop across the head of the filament due to the high conductivity of the trailing plasma channel. When the filament strikes the surface, this voltage is transferred to the resulting sheath and into the material of the surface. The degree of electric field compression depends on the dielectric constant ε/ε 0 of the surface. Upon intersection of the filament with the surface, the electric fields in the resulting sheath can exceed 400-800 kV cm −1 , with larger values corresponding to larger ε/ε 0. When accelerated in these fields, ions can gain energies across their mean free path (0.5-1 µm) up to 20 eV for dielectrics with low ε/ε 0 and up to 150 eV for dielectrics with high ε/ε 0 , albeit only for the duration of the intersection of the streamer with the surface of a few ns. In this paper we report on results from a computational investigation of the ion energy and angular distributions (IEADs) incident on dielectric flat surfaces resulting from the intersection of DBD filaments sustained in atmospheric pressure air. We describe the transient and spatially dependent IEADs as the filament spreads across the polymer.

“…Microplasmas and its diagnostic are a topic of research since about four decades [10][11][12][13][14][15]. The physics of MDs or single DBDs in air and other nitrogen/oxygen gas mixtures has been studied by experimental methods, in particular electrical measurements [16][17][18][19][20][21][22][23], optical emission spectroscopy and imaging [24][25][26][27][28][29], Streak camera recording [19,30], time-correlated single photon counting [31][32][33] and laser diagnostics [34][35][36][37] as well as by simulation and modelling [38][39][40][41][42][43][44][45][46]. In [47] the correlation of the chemical reaction pathways for the oxidation of toluene and trichlorethylene with the physical behaviour of MDs was studied.…”

The development of microdischarges and the inception dynamics of subsequent microdischarges in an electrode arrangement consisting of a metal pin and a hemispherical dielectric-covered electrode, operated in air with a small toluene admixture, is studied. The discharge is operated with sinusoidal high voltage. A gated ICCD camera and a current probe enable the recording of images and current pulses of the single microdischarges, respectively, while the spatio-temporally resolved development is measured with a multidimensional time-correlated single photon counting technique. The overall discharge dynamics changes significantly if a concentration of 35 ppm toluene is added to dry air. A lower high voltage amplitude than in dry air is needed for stable discharge operation. This can be explained by the lower ionization energy of toluene compared to molecular oxygen and nitrogen. The microdischarge development is the same with or without admixture, i.e. a positive (cathode directed) streamer mechanism is observed. Lower mean power is dissipated into the discharge when toluene is admixed. The main effect caused by toluene admixture is the suppression of high-energy microdischarges in case of the cathodic pin half-cycle of the sinusoidal high voltage. The influence on the inception voltage by additional ionization mechanisms and volume memory effects, the consumption of energetic electrons for toluene decomposition reactions, and the modification of the surface by plasma treatment are discussed as possible reasons.
