SOME RESULTS OF THE RESEARCH ON THE FLUTE-TYPE HOLLOW CATHODE DISCHARGE USING A LOW-LIGHT LEVEL TV CAMERA

摘要: 用目前国际上最灵敏的一种微光摄像机电子倍增硅靶微光摄像机对笛形空心阴极放电的着火过程进行了观祭研究;对光发展的机理提出了理论解释;判明了放电的发展存在两个阶段,即阳极与阴极管外空间的自持暗放电阶段和放电通过小孔进入阴极管内的阶段。对应于这两个阶段,存在两个过程,即小孔周围金属表面上的过程和阴极内表面上的过程。根据上述结果,对目前流行的笛形空心阴极的几何参数设计准则进行了讨论。

Abstract: The breakdown processes of the flute-type hollow cathode discharge was observed by a low-light level TV eamera of the SEM (Silicon Electron Multiplication) type, the most sensitive one of low-light level cameras of modern industry. An explantion for the mechanism of light developmen was presented. The light development was divided into two stages, i.e., the stage (1st stage) of self-sustained dark discharge developed in the space between the anode bar and the outer-side of the flute tube, and the stage (2nd stage) of entering of dischage through the hole into the flute tube. corresponding to the two stages, there are two -processes, one existing at the metal surface around the hble and the other at the inner surface of the cathode. According to the above results, a discussion on the current principle of the design of geometrical parameters of the flute type was given. -
