The modified experimental X-ray powder diffraction station on the SR beamline no. 2 of VEPP-3 storage ring

Resumo

Modernization of the experimental station mounted on the beamline No. 2 of VEPP-3 synchrotron radiation electron storage ring at Siberian Synchrotron and Terahertz Radiation Center and intended for X-ray diffraction studies of the structure and phase composition of functional materials with high angular resolution and the possibility of using the effect of resonance scattering has been done. In operating mode the diffractometer of the beamline is equipped with a perfect flat analyzer crystal Ge(111), located in front of the detector. XRD patterns can be obtained in the range of photon energies from 7 keV to 18 keV (or wavelength range ~0.18÷0.07 nm). The angular range of the X-ray registration is limited to 2θ = 140°. The work was performed using a complex VEPP-3/VEPP-4.
