在一个小型化的电容耦合冷大气压等离子体射流中，产生了原子氧，射流工作在氦基气流中，其中含有少量的分子氧混合物。用氙气定标的双光子激光诱导荧光光谱(TALIF)研究了原子氧在放电通道中的积累及其在流出物中的进一步衰减。测量了从放电核心通过过渡区进入流出物的纵向和横向原子氧分布。特别强调了在高压下碰撞猝灭的影响。
Inside a miniaturized capacitively coupled cold atmospheric pressure plasma jet operated at a helium base gas flow with a minor molecular oxygen admixture atomic oxygen is created. The build up of atomic oxygen along the discharge channel and its further decay in the effluent is investigated by means of xenon calibrated two photon laser induced fluorescence spectroscopy (TALIF). The longitudinal and the transversal atomic oxygen distribution is measured from the discharge core through the transition area into the effluent. A particular emphasis is set on the influence of collisional quenching at elevated pressures.
