Abstract

Combined experimental and numerical studies of the cathode fall layer parameters of the self-sustained normal direct current glow discharge in helium at atmospheric pressure with different cathode shapes (planar and rod cathode and planar one with a hole) are presented. It is shown that the cathode shape significantly influences the voltage-current characteristics, spatial distribution of temperature and electric field. Simulation results according to numerical two-dimensional model based on drift-diffusion theory exhibit reasonably good agreement with experiment for discharge with planar and rod cathodes.

常压下不同阴极形状的辉光放电特性

结合实验和数值研究了不同阴极形状（平面棒状阴极和带空穴的平面阴极）的常压下氦自持直流电辉光放电阴极落层参数。结果表明，阴极形状对电压电流特性、温度和电场的空间分布有显著影响。基于漂移扩散理论的二维数值模型模拟结果与实验结果吻合较好。
