Experimental Study of the Method of X-ray Phase-Contrast Microscopy Using a Nanofocusing Lens at KISI-Kurchatov Synchrotron Source

The results of the experimental study at the KISI-Kurchatov synchrotron source of the new phase-contrast imaging scheme for micro-objects using a nanofocusing compound refractive lens are presented. Visualization with submicron spatial resolution of a Fresnel zone plate with the width of the outer zones less than 0.5 µm is demonstrated. It is found that in the performed experiments the main contribution to the instrumental function, which limits the spatial resolution, is due to the vibrations of the optical scheme elements. The possibility of using the proposed scheme for estimating the beam transverse size at the focus of the compound refractive lens, with allowance for the instrumental function, is demonstrated.
