Abstract

We demonstrate how to use a cylindrical Bragg-Fresnel multilayer focusing system instead of spherical mirrors for two-dimensional focalization. We performed our tests at 8 keV with a collimated x-ray tube having an apparent anode source size of 75 microm x 100 microm. These tests demonstrate that focalization can be obtained within <20 microm. This offers new possibilities in optical systems for collimators and fine focusing of x-rays, especially for synchrotron radiation sources.
