Fig. 1

a Schematic diagram of the experimental setup. The gas flow is indicated by the blue arrow. The plasma jet extends along the z-axis. HVE, GE, PMT, and ICCD mean the high-voltage electrode, ground electrode, photomultiplier tube, and intensified charge-coupled device, respectively. b The electrostatic field pattern of the cylindrical dielectric-barrier discharge (DBD), modeled by imposing a potential 11 kV between the electrodes. The relative permittivity of quartz tube is set as 3.7. c The distribution of electric field along the central axis of the quartz tube. The blue circles are the simulation data of electric field. The position of HVE and GE is marked by the red arrow. The shaded region is introduced in order to focus the attention on the area, where a plasma jet could be produced.
