摘要
设计并搭建了一套反射镜损耗增量的实时测量系统,实验得到反射镜损耗变化曲线。结果表明,该系统能有效地监测反射镜损耗在等离子体环境中变化的过程,并揭示损耗变化规律,并发现实际损耗增量和与等离子体作用后的自然放置时间密切相关;改变放电电流和腔体气压,损耗增量幅度明显不同。测量结果为等离子体作用下反射镜损耗变化机理的研究提供了实验依据。
Abstract
A new system for the real-time loss increment measurement of reflecting mirrors is designed and built, and the loss change curve of reflecting mirrors is gained. The results show that the system is capable of effectively monitoring the loss change process of reflecting mirrors in the plasma environment and can reveal the change law. The actual loss increment is closely related to the natural standing time after the interaction of reflectors with plasma. The curve amplitude of loss change is quite different when the discharging current and the cavity pressure change. These measurement results can provide an experimental evidence for the study of the loss change mechanism of reflectors under the action of plasma.
