This paper presents the application of two classical models to high-resolution electric field measurements carried out in a hollow cathode discharge operated in pure hydrogen plasma. The electric field determination has been done via the Stark shifting and splitting of the 2S level of hydrogen, followed by optogalvanic detection. Two classical models, Rickards' and Wronski's, are applied to these measurements with the objective of obtaining a first estimation on the discharge dynamics. The chosen models provide an idea of the ions movement, their energy and their mean free path at the cathode fall region, as well as the electric field strength behaviour depending on the discharge characteristics.

经典模型在氢辉光放电高分辨率电场强度中的应用

本文介绍了两种经典模型在纯氢等离子体中空心阴极放电中进行高分辨率电场测量的应用。电场测定是通过氢的 2S 级的斯塔克位移和分裂完成的，然后是光电流检测。两个经典模型 Rickards 和 Wronski 被应用于这些测量，目的是获得对放电动力学的初步估计。所选模型提供了离子运动、它们的能量和它们在阴极下降区的平均自由程的概念，以及取决于放电特性的电场强度行为。
