NW2A Time-resolved XAFS and XRD

Techniques

XAFS(X-ray Absorption Fine Structure)

  • Energy range: White X-ray or 5 – 25 keV
  • Transmission mode: Ionization chamber
  • Fluorescent mode: Lytle detector

Time-resolved XAFS (DXAFS)

  • Transmission mode with polychromator
  • Photo diode array detector
  • Si-microstrip detector (XSTRIP)

XRD

  • Equipment for XRD is maintained by user group (TITECH)

Other experimental with white or monochromatized X-ray
