Scatterless hybrid metal-single-crystal slit for small-angle X-ray scattering and high-resolution X-ray diffraction

A hybrid design consisting of a single-crystal tip bonded to a tapered metal base with a large tilt angle to the beam practically eliminates parasitic slit scattering in X-ray diffraction apparatus, leading to a single-aperture small-angle X-ray scattering instrument design with enhanced intensity and higher resolution.
