Here we present an approach that directly forms a source image in an extremely small focal spot, achieving 7 nm focusing, in both transverse dimensions, of 9.1 keV XFELs with the extremely high intensity of 1.45 × 1022 W cm−2. This was made possible by a scheme combining...
In brief, the CVI process is a very useful technique that can create different matrix compositions and high purity matrices at low processing temperatures that do not damage the fibers while tailing the microstructure. However, the major shortcomings of CVI is the very slow rate of deposition, le...
The film formation apparatus 600 includes a vapor deposition source 610 that accommodates a material of the multilayer film, such as the stress compensation layer 14 and the reflection layer 16, formed on the substrate 12, a shutter 620, and a substrate holder 630 that holds the substrate 12...
