This instrument combines divergent optics with a displex closed-cycle He refrigerator



Features:

  • Scintag XDS2000 vertical Ø/Ô goniometer
  • Cu,Mo, Cr, Co, Ag, and Fe X-ray targets
  • Displex closed-cycle Herefrigerator (10 K to 300 K)
  • Cold sample loading
  • Diffraction side graphite monochromator and scintallation detector

Applications:

  • In-situ process simulation
  • Lattice thermal expansion coefficients
  • Oxidaton/reduction kinetics
  • Phase equilibria studies
  • Order/disorder transformations
  • Single-crystal diffraction
  • Rietveld analysis
