Abstract: Pattern of hexagon with line has been found for the first time in dielectric barrier discharge system. An intensified charge-coupled device camera and photomultiplier tubes were used to investigate the spatiotemporal structure and temporal correlation of the luminescent pattern. It is found that the luminescent pattern is composed of three sets of substructures: the center point in the hexagon, the point on the hexagon;the line between two points of the hexagon and the halo of the hexagon. Lets call them C(center), V(vertex)+L(line), H(halo). All of their discharges occur at the rising edge of the voltage. The optical signals at V and L were measured by two photomultiplier tubes simultaneously.It is found that both of their discharge in the second current pulse are random. Photos with exposure time of 50 μs were taken by high speed video camera, the results show that L is composed of random filaments.
