The aim of the work was to find the optimal way to set up an experiment for spectroscopic study of the dissociative recombination of molecular ions with electrons in low electron density plasma at low gas pressure. In such an experiment, the influence of inelastic atom–atom collisions on the distribution of the DR flux over the excited atomic levels can be excluded. The first results of an experiment on combining a low-frequency barrier discharge (DBD) in neon at a pressure of less than 1 Torr with a pulsed radio-frequency (RF) induction discharge are presented. To create the plasma, we used DBD in a cylindrical glass tube with an inner diameter of 3.9 cm, which forms the spatial distribution of electron density with a minimum on the axis of the tube. The evolution of such a spatial distribution due to ambipolar diffusion in the initial stage of plasma decay provides an influx of charged particles to the center of the discharge tube, which increases the afterglow duration and he...

低压DBD和RF感应放电的叠加，用于在衰减等离子体中解离重组的光谱研究

这项工作的目的是找到一种最佳方法，以建立一个用于在低气压下在低电子密度等离子体中对分子离子与电子进行离解重组的光谱研究的实验。在这样的实验中，可以排除非弹性原子与原子碰撞对DR通量在激发原子能级上的分布的影响。给出了将压力小于1 Torr的氖气中的低频势垒放电（DBD）与脉冲射频（RF）感应放电相结合的实验的第一结果。为了产生等离子体，我们在内径为3.9 cm的圆柱形玻璃管中使用了DBD，这形成了电子密度在管轴上最小的空间分布。
