研究了硬x射线自由电子激光（XFELs）对铂/碳多层膜的辐照损伤。在这项研究中，为了测试铂/碳多层材料在未来XFEL聚焦应用中的应用，我们在几乎完全符合实际使用条件的情况下评估了这些结构。用XFEL测量了多层膜的x射线反射率，并用透射电镜观察了经XFEL辐照后的多层膜的截面。我们使用了光子能量为10kev的非单色光束。我们证实，多层材料的使用条件强度足以低于铂/碳多层材料的击穿阈值。
We evaluated the irradiation damage induced to platinum/carbon multilayers induced by hard X-ray free-electron lasers (XFELs). In this study, in order to test the use of the platinum/carbon multilayers for future XFEL focusing applications, we evaluated the structures in almost exactly the condition in which they would actually be used. The X-ray reflectivity of the multilayers was measured by using XFELs, and a cross-section of the multilayer that was irradiated by an XFEL was observed by transmission electron microscopy. We used a non-monochromatic beam at a photon energy of 10 keV. We confirmed that the intensity of the conditions under which the multilayers are to be used is sufficiently lower than the breakdown threshold of platinum/carbon multilayers.
