Herewith, we present the optical design of the «Structural Diagnostics» beamline developed for a fourth generation synchrotron radiation (SR) source SRF “SKIF”. The multi section beamline is based on a superconducting undulator (see table below) and will have a total of 4 experimental instruments, three will use fixed energy side branches and the fourth one located on the straight section will have the option of wide energy spectrum. A variety of diffraction experiments can be accomplished simultaneously at this beamline thanks to such a design. The four aforementioned sections are: High-resolution powder diffraction (straight section 1-2-1); In situ diffraction (side section 1-2-2); Single-crystal X-ray diffraction (side section 1-2-3); Small angle X-ray scattering (side section 1-2-4).
Scheme. Optical train of the High-resolution powder diffraction (straight section 1-2-1).
Calculated spot size at each one of the experimental sections as well as expected fluxes will be presented. Heat management for optical components will be also discussed.
