Publikováno v: Journal of Applied Crystallography. 54:730-738

A four-bounce monochromator assembly composed of Ge(111) and Ge(220) monolithic channel-cut monochromators with V-shaped channels in a quasi-dispersive configuration is presented. The assembly provides an optimal design in terms of the highest transm

Surface nanomachining based on single-point diamond turning is a viable technology for the preparation of high-quality surfaces. It found its first extensive use in infrared optics, but it is also attractive for X-ray optics. The challenge is that th

Study of surface quality and subsurface damage of germanium optics produced by single point diamond nanomachining

Autor: Jozef Keckes, Zdenko Zápražný, Petr Mikulík, Peter Siffalovic, Thu Nhi Tran Thi, Eva Majkova, Yuriy Halahovets, Matej Jergel, Igor MatẤko, D. Korytár

Publikováno v: EUV and X-ray Optics: Synergy between Laboratory and Space VI.

Single point diamond nanomachining allows to finish surfaces of some hard-to-machine brittle materials as for example germanium with high shape accuracy, low surface roughness and low subsurface damage. Quality of these surfaces is sufficient when in

Monolithic two-dimensional beam compressor for hard x-ray beams

Autor: Tilo Baumbach, Petr Mikulík, Claudio Ferrari, Lukas Helfen, D. Korytár, Nicola Verdi, P. Vagovič, Alan Kuběna

Publikováno v: Journal of Physics D: Applied Physics. 38:A208-A212

Using asymmetric diffraction in grazing incidence or in grazing emergence it is possible to expand or compress an x-ray beam in one dimension. Combining two asymmetric diffractions with non-coplanar planes of diffraction it is possible to obtain two-

In the first part of the paper [D. Korytar and P. Bohacek: Czech. J. Phys. 50 (2000) 841] a three-dimensional reciprocal space concept based on two-beam dynamical theory of X-ray diffraction has been applied for studying the general case of a flat as

Two-beam dynamical approach to multiple successive diffractors in X-ray crystal optics

Autor: D. Korytár, P. Boháček, I. Bešše

Publikováno v: Czechoslovak Journal of Physics. 46:1011-1025

To devise and optimise new monolithic components for X-ray diffraction optics more and more refined theoretical procedures are required. In addition to the simple geometrical approach utilising the vector Bragg equation, the two-beam dynamical approa
