Microdischarges (MDs) in a sinusoidally driven barrier corona discharge, operated in dry air at atmospheric pressure, are investigated using time-correlated single photon counting (TC-SPC) technique, electrical measurements (applied voltage and current pulses) and ICCD images. In the current contribution, results of the cathodic pin half-cycle are presented. Results of the anodic pin half-cycle were presented in a previous study (Jahanbakhsh et al 2018 Plasma Sources Sci. Technol. 27 115011). In the cathodic pin half-cycle appearance phase and current pulse amplitude of the MDs have an erratic behavior. Hence, a statistical study of the current pulse amplitudes is conducted, and it is correlated to the phase-resolved spatio-temporal development of the MDs, obtained from TC-SPC recordings. This study indicates that the breakdown and development of the MDs is dependent on their inception phase, which is related to the discharge activity in preceding (anodic pi...

带有阴极金属销的势垒电晕装置中单个微放电的实验研究

使用时间相关的单光子计数(TC-SPC)技术,电测量(施加的电压和电流脉冲)和ICCD图像,研究了正弦驱动的势垒电晕放电中的微放电(MDs),该放电在大气压下于干燥空气中运行。在目前的贡献中,提出了阴极销半周期的结果。阳极销半周期的结果已在先前的研究中提出(Jahanbakhsh等人2018 Plasma Sources Sci.Technol.27 115011)。在阴极引脚的半周期出现时,MD的相位和电流脉冲幅度具有不稳定的行为。因此,对当前脉冲幅度进行了统计研究,并将其与从TC-SPC记录中获得的MD的相位分辨时空发展相关。
