大气压氦气多脉冲辉光放电径向光学演化过程
Radial Optical Development of a Multipeak Glow Discharge in Atmospheric-pressure Helium
摘要
Abstract
Radial development of dielectric barrier discharge （DBD） and its influencing factors are of importance in studying the mechanism of low-temperature plasmas. Three-pulse dielectric barrier glow discharge was carried out using an ITO transparent electrode. Short exposure time images from side direction of the gas gap were taken with an intensified charge-coupled device （ICCD） to diagnosedischarge modes. And the radial development was discussed by taking end-view images and drawing the corresponding three-dimensional light distribution. It was found that the discharge first originates at the peripheral part of the electrode, develops to the center and then turns to the periphery again and declines gradually. And the discharge develops more strongly in the central part as the sequence of pulses increases. The current limitation of the electrode structure together with the applied voltage and the surface charges plays a key role in the different discharging time in the radial direction.关键词
