“…Current x-ray radiography approaches at large laser facilities use area backlighting methods to generate efficient x-ray sources for imaging by irradiating thin foils [12]. By placing a thin slit between the backlighter and target, the x-ray source is reduced in size, allowing for higher resolution via phase-contrast imaging (PCI) or refraction-enhanced radiography (RER) [13][14][15], which is itself based on the work of Pogany et al [19,20]. In RER, an x-ray source is used to illuminate a target through a slit and the resulting refracted x-rays are recorded on an x-ray framing camera.…”

Warm dense matter is a region of phase space that is of high interest to multiple scientific communities ranging from astrophysics to inertial confinement fusion. Further understanding of the conditions and properties of this complex state of matter necessitates experimental benchmarking of the current theoretical models. Benchmarking of transport properties like conductivity and diffusivity has been scarce because they are small and slow processes that require micron-level resolution to see. We discuss development of a radiography platform designed to allow for measurement of these properties at large laser facilities such as the OMEGA Laser.

“…made possible by the slits we have used -novel 1 𝜇m-wide slits were created specifically for our platform, and are to the authors' knowledge the smallest slits used at a large laser facility thus far, five times narrower than previous examples [15].…”
