摘要

等离子喷射器是一种大气压等离子源，可在等离子设备的边界外投射流线。这些流束产生的电场可在流束接触基底之前在基底上产生电流。这种位移电流与流线距离表面的远近密切相关。我们建立了一个流线向基底移动的基本模型，可以根据测量到的位移电流确定流线的位置和速度。这种简单的方法与光学成像设备显示出良好的一致性，并能提供一种快速量化流线速度的方法。

Determining the streamer velocity in an atmospheric pressure plasma jet from the target substrate current

Plasma jets are an atmospheric pressure plasma source that projects streamers outside the bounds of the plasma device. The electric field produced by these streamers can generate a current in the substrate before the streamer contacts the substrate. This displacement current is a strong function of the proximity of the streamer to the surface. We develop a basic model of the streamer traveling towards the substrate that can determine the streamer location and velocity from the measured displacement current. This simple approach shows good agreement with optical imaging equipment and can provide a means to rapidly quantify the streamer velocity.
