用透射电子显微镜(TEM)和电子能量损失谱(EELS)研究了核级石墨的辐照损伤。原子尺度上的结构变化和化学键合,以及它们之间的关系特别令人感兴趣。TEM被用来研究在1.92× 10 8电子nm− 2的电子束曝光后原子尺度上核级石墨的损伤。在这些实验期间,EELS光谱也被定期收集,以通过分析碳K边的变化来记录化学键合和结构无序的变化。“PyroMaN”研究小组的图像分析软件基于(002)条纹分析提供了进一步的信息。该软件被施加到电子辐照的处女“桩级A”(PGA)石墨的显微照片,以量化从电子束曝光的损害程度。
Radiation damage in nuclear grade graphite has been investigated using transmission electron microscopy (TEM) and electron energy loss spectroscopy (EELS). Changes in the structure on the atomic scale and chemical bonding, and the relationship between each were of particular interest. TEM was used to study damage in nuclear grade graphite on the atomic scale following 1.92× 10 8 electrons nm− 2 of electron beam exposure. During these experiments EELS spectra were also collected periodically to record changes in chemical bonding and structural disorder, by analysing the changes of the carbon K-edge. Image analysis software from the'PyroMaN'research group provides further information, based on (002) fringe analysis. The software was applied to the micrographs of electron irradiated virgin'Pile Grade A'(PGA) graphite to quantify the extent of damage from electron beam exposure.
