本文介绍了Tore Supra托卡马克装置内一年实验周期内暴露的镜样品（钼、不锈钢和铜）的尸检分析结果。镜子在实验过程中没有受到保护，因此暴露于容器壁的辉光放电调节和工作放电。暴露后，发现所有样品都被侵蚀，同时涂有薄的污染存款。我们注意到，所观察到的侵蚀不能用公布的溅射产率来描述。特别地，与从文献中已知的大约2.5和大约10的相应因子相比，不锈钢和铜的腐蚀之间的差异超过10倍，不锈钢和钼的腐蚀之间的差异小于2倍。试图将这些观察结果与碳在不同基材上的不同粘附系数相关联。
In this paper the results of post-mortem analysis of mirror samples (molybdenum, stainless steel and copper) exposed for the 1 year experimental campaign inside the Tore Supra tokamak are presented. The mirrors were not protected during the experiment and therefore were exposed both to glow discharge conditioning of the vessel walls and to working discharges. After exposure, all samples were found to be eroded and at the same time were coated with a thin contaminating deposit. We pay attention to the fact, that the observed erosion cannot be described using the published sputtering yields. In particular, the difference between the erosion of stainless steel and copper exceeded a factor of 10 and the difference between the erosion of stainless steel and molybdenum was less than a factor of 2 in comparison with the corresponding factors of approximately 2.5 and apprximately 10 known from the literature. An attempt is made to correlate these observations with the different sticking coefficients of carbon on to different substrates.
