| 1 | Ionization waves in nanosecond pulsed atmospheric pressure plasma jets in argon显示文摘Typical ionization waves(IWs)are observed during the propagation of nanosecond pulsed atmospheric pressure plasma jets(APPJs)with argon flow,combining both the measurement of the axial electric field(Ez)and the temporal resolved optical imaging.The movement of the luminous APPJ head is recognized as the development of the IW front,accompanied with the propagation of the peak electric field.Especially,the radial distribution of Ez transits from a central peak profile before the IW front arrives to a hollow profile after the pass of the IW front.As for the temporal Ez trend,there is a mode transition from the single-peak feature under a low peak voltage to the double-peak feature under a higher peak voltage,indicating the existence of both primary and secondary IWs.The effect of target conditions on the IWs in APPJs is also explored.With a metal target,no residual electric field is observed before imposing the high-voltage pulses.However,with a dielectric target,the residual surface charges generate a back-ground electric field in the opposite direction to that during IW propagation.In the free APPJ(with no target),on the voltage falling edge,a negative electric field drives the electron flow to compensate the positive ions left over during the forward IW propa-gation on the voltage rising edge. | Bangdou Huang Cheng Zhang Wenchao Zhu Xinpei Lu Tao Shao | 2021 | High Voltage2021，6，4： | 1 |
