Paper Abstract

The photoelectric measurement of the hexagon pattern in dielectric barrier discharge is performed. By measuring the current signals and the light signals of the hexagon pattern, it is found that there are three main pulses in both of the total current signal and the total light signal. The light signal of a fixed filament in hexagon pattern is also measured. It is found that the spatial location of the filament is unchanged, while its discharge moment is changed with the time, which is probably corresponding to the first pulse, the second pulse or the third pulse of the total light signal. However, no matter when it discharges, the light pulse width for one filament is almost 30 ns, and the ratio of the rising edge to the falling edge of the pulse is about 1:1.88. In addition, the properties of hexagon patterns with the increased gas pressure are investigated. The pattern bifurcation sequence is changed accordingly, and pulse widths of the light signals of the hexagon pattern rises with increasing the gas pressure, which changes from 30ns (at 0.3atm) to 107ns (at 1atm), and the ratio changes from 1:1.88 to 1:3.
