摘要: 氩离子枪主要由离子源、加速电极、聚焦透镜和控制电源构成,可以产生并发射氩离子束,用于样品的表面清洁处理、表面刻蚀或深度分析,是表面分析和纳米科技装置中的重要构成之一。文章介绍国产氩离子枪的设计原理和测试结果,氩离子的加速电压可达2 kV,在工作距离150 mm和氩气分压为2.0×10-3 Pa的情况下,可产生4.5 mA的氩离子束流,束斑的直径在10-20 mm之间可调。Abstract: The ion gun generates Ar ion beams with well defined space and energy distribu-tion. It is composed of ion source, extraction grid, collimator lens structure and electronics controller. It is an important equipment in surface science and nanotechnology, which provides a means to sputter or etch a surface and generates an elemental or chemical depth profile. In this article, a domestic Ar ion gun with 2 kV beam voltage and 4.5μA beam current is introduced.
