这篇博士论文描述了钨暴露在类似聚变的环境中时发生的损伤。这本书介绍了关于使用掠入射小角度X射线散射（GISAXS）来测量暴露于氦等离子体的钨中纳米气泡形成的开创性工作。在氦等离子体暴露期间金属内纳米级气泡形成的现象可导致材料性质的不期望的变化，例如复杂的纳米级表面改性或热导率的降低。作为这项工作的结果，现在可以量化纳米气泡在不同材料和不同等离子体条件下的行为变化。2015年，作者发表了第一篇关于钨中氦诱导纳米气泡形成的GISAXS研究，证明了使用GISAXS进行这项工作的可行性。这篇论文引起了国际聚变界的极大兴趣，并被选为《核聚变》杂志的亮点之一。
This PhD thesis characterises the damage that occurs in tungsten when it is exposed to a fusion-like environment. The book presents pioneering work on the use of grazing-incidence small-angle X-ray scattering (GISAXS) to measure nano-bubble formation in tungsten exposed to helium plasma. The phenomenon of nanoscale bubble formation within metals during helium plasma exposure can lead to undesirable changes in the material properties, such as complex nanoscale surface modification or a reduction in thermal conductivity. As a result of this work, it is now possible to quantify how nanobubble behaviour changes within different materials, and under different plasma conditions. In 2015 the author published the first GISAXS study of helium-induced nanobubble formation in tungsten, demonstrating the viability of using GISAXS for this work. This paper has generated significant interest from the international fusion community and was selected as one of the highlights for the journal Nuclear Fusion.
