The Panalytical Empyrean is the Centers newest multipurpose high-resolution x-ray diffractometer. With similar capabilities to the Panalytical XPert x-ray diffractomer, it is a high resolution diffraction system consisting of a highly monochromatic beam with a well-defined wavelength and equatorial divergence that operates in a q/q geometry. An X-ray mirror and a high-resolution monochromator are placed in line to deliver an incident X-ray beam that is not only highly monochromatic with a low divergence, but also has a high intensity. Reflectometry measurements can also be performed to identify layer thickness, density and surface roughness.  Optics can be readily switched to an x-ray mirror alone where higher intensity is needed.  Major new capabilities are achieved because the system includes the PIXcel3D area detector that can be operated in several modes including one that allows the acquisition of ultrafast reciprocal lattice maps.

High Resolution Setup

    • Four-circle and z translation sample stage on high resolution goniometer.
      Absolute angular resolution = 0.0001 degrees for both the incident beam and detector
    • Hybrid monochromater consisting of closely coupled x-ray mirror and 4 bounce Ge 220 monochromator.
      Resolution = 22 arc-seconds or less for Si 111 reflection
    • Diffracted beam optics
      Three bounce Ge 220 analyzer crystal.  Resolution = 12 arc-second  or in a separate detector path, the PIXcel3D area detector with 255 by 255 0.055mm detectors.

Reflectometry setup

  • For high resolution: combine the Hybrid monochromator with the three bounce Ge 220 analyzer crystal.
  • For high flux combine the x-ray mirror with the PIXcel3D area detector.
