摘要:
主要通过实验的手段，系统研究了钡钨空心阴极的等离子体放电特性及其工作模式。实验中，使空心阴极工作在三极管构型下，调节相应的放电参数，详细分析钡钨空心阴极放电特性的变化规律、存在的放电模式及其转化规律。最后得到结论：钡钨空心阴极放电表现为羽毛状、亮斑状和弥漫状等3种典型的工作模式；不同放电模式可以用放电电流、放电电压及其振荡特性进行判定和区分；随着放电参数的变化，几种放电模式之间可以相互转化。
Abstract:
The plasma discharge characteristics and different discharge modes of BaW hollow cathode are systematically studied via experiment in this paper. During the experiment, the relevant discharge parameters of hollow cathode working in triode configuration were adjusted, and the discharge characteristics, the possible discharge modes and the transition between different discharge modes of BaW hollow cathode were analyzed in detail. The conclusions that the BaW Hollow ca- thode has three distinct discharge modes (plume mode, spot mode and diffuse mode) were acquired at the end. The three modes can be clearly distinguished by the change of discharge current, discharge voltage and their oscillation characteristics. Furthermore, the transition among the three modes can be realized as the discharge parameter changes.
