At the end of 2023 a study on Characterization of Pt-coated twin paraboloidal laboratory capillary high energy X-ray optics by Anthony Seret, Jan Kehres, Carsten Gundlach, Ulrik Lund Olsen, Henning Friis Poulsen, Dorte Juul Jensen, Mark Cordier, Benjamin Stripe, Wenbing Yun, and Yubin Zhang have been published in the journal Optics Express.
Key findings from the research include the observation of an 8.5 µm focal spot with a divergence angle of 0.59°. The optics demonstrated efficiency and gain across different photon energy levels, with a focal point tailored for optimum performance at 32 keV. The study emphasizes the challenges faced in creating such high-energy optics for laboratory instruments, addressing issues related to beam divergence and polychromatic X-rays.
The team behind this breakthrough includes researchers from Sigray, showcasing a dedication to advancing X-ray optics for laboratory applications. The optics, manufactured using amorphous borosilicate and platinum coating, overcome traditional challenges associated with heavy element materials like platinum, gold, and tungsten.
The research also highlights the versatility of these optics in X-ray microdiffraction applications. The team successfully demonstrated the optics' capabilities by analyzing polycrystalline aluminum, showcasing the potential for non-destructive and high-resolution material characterization.
The study opens up possibilities for further developments in laboratory X-ray sources, especially in the realm of characterizing large and dense materials such as metals. The groundbreaking optics present a major leap forward in achieving finer spatial resolution and more intense signals in laboratory settings.
These findings mark a significant milestone in X-ray optics research, paving the way for enhanced capabilities in material science and non-destructive analysis. The research paper provides a comprehensive exploration of the design principles, manufacturing challenges, and practical applications of these Pt-coated twin paraboloidal optics.
