(Invited) On Several Atmospheric Pressure Plasma Sources

Abstract

In this talk, firstly, several plasma jets developed in our group are presented, including a nobble gas plasma jet for root canal treatment and four air plasma jet devices [1, 2] . Secondly, several interesting physics phenomena of plasma jets are introduced, such as the repeatability of the plasma bullet, the plasma interruption behavior, the plasma transfer dielectric phenomenon, and the appearance of multiple plasma bullet per voltage pulse [2-4] . Thirdly, the state-of-the-art on the measurement of VUV emission of atmospheric pressure air plasma is discussed and our results by using differential pumping system as EUV window are presented [5] . Fourthly , several different configurations of nonequal gap distance DBD are described [6, 7] . Finally, an atmospheric pressure glow discharge in air stabilized by a magnetic field and its application on nitrogen fixation are rep orted. Li, J. Liu, X.
