摘要
论文探索了光阴极玻璃基底的热清洁和离子清洁对提高光阴极灵敏度的影响。通过不同玻璃基底玻璃成分的研究,证明玻璃中的碱金属的含量会影响到光阴极灵敏度的高低。通过表面张力分析,证明对光阴极玻璃基底进行热清洁和离子清洁可以增加玻璃表面的表面能,对提高光阴极的灵敏度有一定的作用。通过XPS分析,证明离子清洁可以提高光阴极的灵敏度,然而离子清洁过度会带来碳污染,从而降低光阴极灵敏度的稳定性。
The effect of hot cleaning and ion cleaning for photocathode glass substrate on improving the photocathode sensitivity is researched. It is shown from the analysis of glass ingredients of different glass substrates that the alkali metal content in glass may affect the photocathode sensitivity. It is shown from the analysis of surface tension that the hot and ion cleaning of photocathode glass substrate can increase the certain degree. It is also shown from XPS analysis that the ion cleaning can be used to improve the sensitivity of photocathode, however, an excess ion cleaning may cause C contamination to decrease the stability of photocathode sensitivity.
