DESCRIPTION:Speakers: Zakhar Vinokurov (BIC SB RAS)\nHerewith\, we present
  the optical design of the «Structural Diagnostics» beamline developed f
 or a fourth generation synchrotron radiation (SR) source SRF “SKIF”. T
 he multi section beamline is based on a superconducting undulator (see tab
 le 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 diffra
 ction experiments can be accomplished simultaneously at this beamline than
 ks to such a design. The four aforementioned sections are: High-resolution
  powder diffraction (straight section 1-2-1)\; In situ diffraction (side s
 ection 1-2-2)\; Single-crystal X-ray diffraction (side section 1-2-3)\; Sm
 all angle X-ray scattering (side section 1-2-4).   \n  \n![Scheme. Optical
  train of the High-resolution powder diffraction (straight section 1-2-1).
    \nCalculated spot size at each one of the experimental sections as well
  as expected fluxes will be presented. Heat management for optical compone
 nts will be also discussed.   \n][1]   \n  \nTable. Main machine parameter
