Abstract

We report the results of an experimental study of Ne II 369.421 nm, 371.308 nm, and 372.711 nm spectral line shapes by means of the optical emission spectroscopy The spectral lines are recorded in the cathode sheath region of an abnormal glow discharge operated in pure neon and by using different cathode materials: copper (Cu), iron (Fe), and titanium (Ti). The studied lines have complex spectral profiles which enabled us to determine important discharge parameters. In this work we present the correlation between the width of pedestals of the side-on recorded Ne II spectral lines and the electric field strength distribution as well as the correlation between line pedestal width and the distance of the recording position from the cathode.

异常辉光放电的阴极鞘中的Ne II谱线

摘要

我们报告了通过光发射光谱法对Ne II 369.421 nm，371.308 nm和372.711 nm光谱线形状进行实验研究的结果。光谱线记录在纯氖灯和纯氖灯操作的异常辉光放电的阴极鞘区域中。通过使用不同的阴极材料：铜（Cu），铁（Fe）和钛（Ti）。所研究的管线具有复杂的光谱轮廓，这使我们能够确定重要的放电参数。在这项工作中，我们介绍了侧面记录的Ne II谱线的谱线宽度与电场强度分布之间的相关性，以及谱线宽度与记录位置与阴极的距离之间的相关性。
