Studies on Focusing Performances of the Bent Crystal Monochromator

  • The triangular crystal is used as monochromator on 4W1C beamline at Beijing Synchrotron Kadiation Facility. Three crystals of Si(111), Si(220) and Si(422) with an oblique-cut angle of 12.16° are employed at the same Bragg angle 23.65°to select monochromatic X-rays with wavelengths of 0.252nm, 0.154nm and 0.089nm,respectively. The triangular crystal is bent to a cylindrical shape to focus the beam in the horizontal direction and to provide focusing monochromatic X-rays for the diffuse scattering station. The theoretic calculations and SHADOW ray-tracing of the optical system are in good agreement with the experimental results.

Abstract: The triangular crystal is used as monochromator on 4W1C beamline at Beijing Synchrotron Kadiation Facility. Three crystals of Si(111), Si(220) and Si(422) with an oblique-cut angle of 12.16° are employed at the same Bragg angle 23.65°to select monochromatic X-rays with wavelengths of 0.252nm, 0.154nm and 0.089nm,respectively. The triangular crystal is bent to a cylindrical shape to focus the beam in the horizontal direction and to provide focusing monochromatic X-rays for the diffuse scattering station. The theoretic calculations and SHADOW ray-tracing of the optical system are in good agreement with the experimental results.
