RCH-2: The Diffraction and Emission Spectroscopy Hutch 

The core equipment is a 5-crystal Johann-type emission spectrometer for high-resolution XANES and XES measurements (right), a six-circle goniometer (center) and a Pilatus-2M detector for  diffraction experiments (left).

Experimental Techniques

  • High resolution powder diffraction (HRXRD)
  • Crystal truncation rods (CTR)
  • Resonant anomalous X-ray reflectivity (RAXR)
  • High-resolution X-ray absorption near-edge structure spectroscopy (HRXANES), X-ray emission spectroscopy (XES) and resonant inelastic X-ray scattering spectroscopy (RIXS)


  • six-circle design (built by HUBER)
  • horizontal and vertical scattering plane
  • high load on sample position (15 kg)
  • sample mounting on x-y-z slide, capillary holders or extra goniometer heads
  • all motions driven by stepper motors and gear boxes
  • angular accuracy better than 0.001° (step 0.0001°)
  • translation accuracy in z: 1 µm and in x and y: 10 µm
  • SPEC-controlled


  • scintillation detector
  • Si-DRIFT detector
  • 2-dimensional position sensitive detector (Pilatus 100k)
  • 2-dimensional position sensitive detector (Pilatus 2M)
