The DICSI small-angle station is developed at the 1.3a beamline of the Siberia-2 storage ring at the Kurchatov Center of Synchrotron Radiation (Russia). The station is intended for X-ray diffraction investigations of the structural dynamics of biological objects with a high time resolution in the small-angle range. The DICSI station is a new version of the station which is based on our previous experience in the development of different stations at the Siberian Synchrotron Center. The OD-3 coordinate detector is used to record the diffraction patterns. The synchrotron beam is monochromatized and collimated with the use of X-ray optical elements, including the system of primary collimators with a focusing monochromator, the polysectional system of focusing mirrors of total external reflection, forming and background slits, a beam attenuator, a primarybeam stop, and evacuated tubes for beam transmission. The station provides measurement of spacings from 1.0 to 100.0 nm in the wavelength range 0.10-0.25 nm with a spectral width ∆λ / λ = 10 -3 -10 -4 .
