Abstract Scope |
Materials serving as a plasma facing components suffer from severe environmental degradation. One of the most dangerous defects are voids or bubbles. These nanosized objects are traditionally studied by means of transmission electron microscopy which may lead to misinterpretation related to imaging parameters. This study explores the possibilities to study bubbles/voids with scanning electron microscopy for better accuracy of the measurements. The modern devices enable to control variety of parameters which enable setting the proper imaging conditions for the direct visualization of the objects in question, including qualitative and quantitative analysis. The latter is very important and usually is neglected in electron microscopy studied due to difficulties related with understanding a spatial distribution of observed objects. Output of such experiments can be further used for advanced modelling or combined with other experiments. Our work focuses on tungsten, however proposed techniques may be easily applied for studies on other materials. |
