AR-NW10A : XAFS (High-Energy) Experiments

Overview

Beamline group 　Group 3 (X-ray Spectroscopy)
Techniques
  • XAFS (X-ray Absorption Spectroscopy)
  • AXS (Anomalous X-ray Scattering)
  • Other experiment with monochromatized X-ray
Features
  • An experimental station has been designed for hard X-ray XAFS experiments.
  • Higher energy region (Max. 42 keV) is available than 2.5-GeV PF’s beamlines.
Area of research
  • Materials Chemistry
  • Materials Engineering
  • Earth and Environmental Science
  • Biological Science etc.
