空心阴极灯的正确保养方法
点击次数:210 发布时间:2019-06-18
   空心阴极灯是一种特殊形式的低压气体放电光源,放电集中于阴极空腔内。当在两极之间施加200V-500V电压时,便产生辉光放电。在电场作用下,电子在飞向阳极的途中,与载气原子碰撞并使之电离,放出二次电子,使电子与正离子数目增加,以维持放电。正离子从电场获得动能。如果正离子的动能足以克服金属阴极表面的晶格能,当其撞击在阴极表面时,就可以将原子从晶格中溅射出来。除溅射作用之外,阴极受热也要导致阴极表面元素的热蒸发。溅射与蒸发出来的原子进入空腔内,再与电子、原子、离子等发生第二类碰撞而受到激发,发射出相应元素的特征的共振辐射。与此同时,HCL所发射的谱线中还包含了内充气、阴极材料和杂质元素等谱线。那么,对于空心阴极灯来说,该怎样正确进行保养呢?
