    The back diffusion processes in Ar, SF6, and Ar + SF6 binary mixtures are analyzed by a Monte Carlo simulation method employing realistic collision cross sections of the respective component gases in the E/N range from 50 to 500 Td. The escape factors in pure Ar are always higher than that of those in pure SF6, and as the SF6 content in the binary mixture increases, the escape factors decrease accordingly. Furthermore, the number of collisions observed for the backscattered electrons before returning to cathode in SF6 are smaller than that of those in Ar, and as the SF6 content in the binary mixture increases, the mean number of collisions of the backscattered electrons decrease accordingly.

    Time-resolved light emission imaging was used to observe the plasma formation at the surface of a dielectric rod serving as a slow-wave supporting structure in an antenna-amplifier Cherenkov maser configuration. Experiments were performed using a quartz rod inserted into the hollow knife-edge cathode of a magnetically insulated foilless diode generating an annular electron beam of 0.9-1.7-kA current. The accelerating voltage pulse was delivered to the diode by a linear induction accelerator; the voltage amplitude ranged from 260 to 380 kV at the full pulse duration of ~ 200 ns. It was shown that the plasma at the rod surface is produced in the vicinity of the cathode edge plane corresponding to the location of the strong tangential electric field component. This plasma appears later than the explosive emission plasma at the cathode edge, and the intensity of light from this plasma increases, while the voltage rises. At voltages below 300 kV, the measured side-view light intensity drastically decreases, which indicates a significant decrease in the plasma density. It has been found that the surface plasma does not propagate along the rod; yet, the presence of plasma at a distance of 5-10 cm from the cathode was registered sporadically at high voltages. The electron emission from the surface plasma was observed as well. View full abstract»

  • A Study on the Long-Term Stability of the Discharge Characteristics by the Small Addition of Nitrogen to Ne–Xe Gas Mixture in AC Plasma Display Panel

    In this paper, the long-term stability of the discharge characteristics in a plasma display panel is investigated with the small addition of nitrogen to the conventional Ne-Xe gas mixture. It is found that the characteristics of temporal variation in discharge voltages and full black brightness are enhanced with nitrogen gas addition, which could result in the reduction of mis-writing probability and the enhancement of image quality. In the study of the temporal variation of discharge voltages via a Vt close curve, it is observed that nitrogen addition suppresses the changes in discharge voltages. Regarding discharge voltage variation, the change in elements on the surface of the phosphor layer and the temporal modification of the protecting layer are investigated with overfrequency discharge aging using secondary-ion mass spectrometry and a scanning electron microscope, respectively. A small change in elements on the surface of the phosphor layer is observed in the panel, with nitrogen being added to the gas mixture. The reduced ion energy with the addition of nitrogen gas is suggested as a potential reason to induce the different variation of MgO transfer characteristics and discharge voltage.

    In this paper, dielectric-barrier discharge plasma was applied to the decolorization and degradation of the azo dyes C.I.Acid Yellow 17 and C.I.Direct Red 31. The experimental results have shown that the decolorization and degradation percentage increases with rising applied voltages and current intensity and decreasing air-gap distances. When the air-gap distances were 4 mm and the voltage was 17 kV, the decolorization and degradation percentages went up to 100% and 91% in 180 s, respectively. Operations under optimum condition also had higher treatment efficiency after about two more minutes of treatment. Time extension after treatment could also lead to the rise of decolorization and degradation percentages. View full abstract»

    We present an approach to increase the area for surface treatment using a nitrogen atmospheric-pressure plasma jet sustained by a pulsed dc power source. This plasma is used for glass surface treatment to quantify the efficiency of the treatment by examination of the water contact angle before and after the treatment. The proposed approach utilizes a glass tube to shield the jet downstream from the ambient air contamination. With this approach, the visible jet length and width increase significantly. The effective area for surface treatment using this jet increases by more than a factor of two. View full abstract»

    An evaluation of the energy density and efficiency of high-voltage capacitors, from various manufacturers, at voltages above their rated level is presented. Characteristics such as decreasing capacitance, decreasing efficiency, and increasing energy density are described. Data are taken from eight capacitors; six of which are composed of varying nonlinear ceramic materials as a dielectric, and the remaining two are wound capacitors, which were chosen to exhibit their linear characteristics. Rapid (1-100 ms) charging and discharging, similar to that of a generator operation at a repetition rate of more than 10 Hz with an ~100-ns pulse, were the conditions simulated in this particular test setup.

    Experimental results for the operation of a device which generates radially propagating pulses of plasma are reported. These are produced from a convoluted arc plasma column formed using a suitably configured magnetic field (B-field). Both quasi-steady-current and alternating-current arc plasmas in atmospheric pressure air have been studied. High-speed photographic records of the convoluted plasma column during the main arcing phase are presented along with video images of propagating plasma clouds formed when the B-field and arc current collapse. Measured time variations of current and arc voltage during the main current phase are correlated with features on the photographic records. Results are presented, showing the effect of different operating conditions upon the propagation rates of the plasma pulses. View full abstract»

    This paper discusses the development and testing of a low-jitter, high-voltage, high-current, and triggered spark-gap switch, designed as part of an intense electron-beam accelerator (IEBA). The voltage/pressure (V/p) curve of the switch was measured for N2 when the gas pressure is 0.10-0.25 MPa with the main gap spacing of 10 mm. In addition, the operating ranges, delay time, and jitter of the switch were measured during the single trigger experiment when the gas pressures were 0.10, 0.15, 0.20, and 0.25 MPa and the trigger voltage was 80 kV. The experimental results showed that the operating ranges of the switch were 25%-94%, 38%-86%, 40%-88%, and 44%-88% of the switch's self-breakdown voltage, and these results also identified a suitable operating condition for the application of the switch on the IEBA. When the gas pressure was 0.25 MPa, the operating voltage was 40 kV, which was about 88% of the self-breakdown voltage, the delay time was 50 ns, and jitter was 1.28 ns. At last, the repetition rate of the switch was measured when the switch was used as the trigger switch of the IEBA. The pulse repetition rate (PRR) is 10 Hz at the operating voltage of 20 kV and peak currents of 40 kA. The PRR is 5 Hz at the operating voltage of up to 40 kV and the peak currents of up to 80 kA. The switch works steadily and reliably. View full abstract»
