摘要:

2010年春季对安装在EAST抽气、硼化和限制器等所在的不同窗口的不锈钢、钨、钼等三种金属第一镜样品进行辐照实验,以初步研究等离子体辐照对第一镜光学特性的影响。辐照后,样品表面出现明显杂质沉积层,沉积层导致第一镜光学特性严重恶化。因此,对第一镜安装有效的保护装置以屏蔽杂质沉积,或应用第一镜原位清洗技术是必要的。

Abstract:

Three different kinds of metal first mirrors made from the stainless steel, tungsten and molybdenum materials were installed on the windows of the puffing, boronization, limiter systems of EAST tokamak, and exposed during the spring experiments of the 2010 to first investigate the influence of the exposure environment on the optical property of the first mirrors. After exposure, the thick contaminant deposit layers were formed on the mirror surface and the optical property degraded seriously because of the deposit layer. Thus, to ensure the lifetime of the first mirror, the effective protective system for the mirror and the in situ cleaning of the mirror surface must be applied.

Key words: First mirror, Exposure, Reflectivity, Deposition, Sputtering
