Description
A new beamline "Structure investigation" will be put into operation in the test mode at the SKIF synchrotron radiation source in 2024. The beamline will have stations: 1) "Precision diffraction / anomalous scattering"; 2) "In situ diffraction"; 3) "Single crystal diffraction"; 4) «USAXS / reflectometry». The stations will supervise accordingly: 1) Institute of Catalysis of the SB RAS; 2) Institute of Solid State Chemistry and Mechanochemistry of the SB RAS; 3) Institute of Inorganic Chemistry of SB RAS; 4) Shubnikov Institute of Crystallography RAS.
The beamline will use the radiation from a 300-pole superconducting undulator with a 1.2 T field. At a photon energy of 7 keV, the brightness will be 4*10 ^ 21 phot / (sec mm^2 mrad^2 0.1% BW). The energy range will be from 5 to 50 keV.
Required channel element will be beam monitor. The monitor will determine both the intensity of the beam and its position with an accuracy of 1 micron. The read out frequency of monitor will be 100 MHz, which will allow to determine the position of the radiation from each bunch of electrons.
A dual monochromator with a fixed output can provide monochromatization from 10^-2 to 10^-4. If necessary, a monochromator can skip a white beam. Focusing mirrors will be used, which will ensure focusing and cutting of high harmonics if necessary.
To work in a high energy area, refractive optics will be used. Both focusing and defocusing lens will be used.
A fast chopper will be used, for investigating of fast processes, with exposure from a single bunch with continuance near 73 ps.
The main detector at the new station will be the coordinate-sensitive detectors DIMEX [1], whose use at the VEPP-3 source and showed great potential possibilities associated with the use of synchrotron radiation for the study of fast processes [2]. Detectors OD-3M [3] and PILATUS will also be used.
