X-ray stations based on cylindrical zoom lenses for nanostructural investigations using synchrotron radiation

The main results of the development of X-ray stations are presented. These stations are intended to solve problems concerning the structural biology of tissues at a high time resolution with the help of synchrotron radiation (SR) generated by the VEPP-3 storage ring (Siberian center of SR, Novosibirsk) and the Siberia-2 storage ring (National Research Centre Kurchatov Institute and the centre of nano-, bio-, information, and cognitive sciences, Moscow). The issues of selecting the optical scheme and basic parameters of X-ray optical systems are discussed. Photographs of the original designs of the constructed equipment are given. A modular approach to designing experimental facilities based on self-contained units and methods of focusing a monochromatic SR beam in the required spectral range have been developed. The technique of X-ray beam focusing by means of optical zoom lenses has been implemented. Experimental results that illustrate the possibilities of the SR-beamline hardware used for X-ray diffraction investigation of different biological objects with the help of different recording systems are presented.
