High-resolution compact multi-stepped X-ray diffractors

Three different types of focusing X-ray diffractors based on multi-stepped geometry were modeled and compared by means of numerical simulations. A prototype of a diffractor based on one of these models was manufactured and tested to compare performances with the simulations. The results support both the feasibility of the multi-stepped design and the expected advantages both in term of spectral resolution and intensity of focused monochromatic radiation.
