摘　　要：文章简要介绍了同轴源原子氧装置的基本结构和工作原理；分析和计算了同轴内导体的受热状况,对内导体的结构进行了优化,使其寿命提高了近10倍,并减少了因天线氧化对真空室的污染；设计了新的试样架,试样架可同时装入4个不同试样；配置了两套紫外光源系统和一套试样光学性能原位测量系统,使装置具备了原子氧与紫外的协同效应,紫外光的波长为185～400nm,辐照度可达2～4个太阳常数；增加了光学性能测量室,试样光学性能可以原位测量。试验结果表明：优化后的原子氧装置能够模拟空间原子氧对材料的剥蚀效应。The configuration and operating process of the co-axis source atomic oxygen ground simulation facility are described in this paper.We've analyzed the thermal state of inner-conductor and optimized its structure.The life-span of the new inner-conductor is about ten times long compared with the old one,while the contamination created by the inner-conductor has been decreased greatly.We have designed a new sample tray,which four samples can be placed in.The facility is equipped with two sets of UV lights source and one suit of optical properties in-situ measurement system.The wavelength of UV lights is at the range of 200～400nm,radiation intensity is about 2～4 EUVS.Synergistic effects of atomic oxygen with UV lights can be conducted and optical properties of materials can be measured in vacuum chamber.
