The SUT‐NANOTEC‐SLRI beamline was constructed in 2012 as the flagship of the SUT‐NANOTEC‐SLRI Joint Research Facility for Synchrotron Utilization, co‐established by Suranaree University of Technology (SUT), National Nanotechnology Center (NANOTEC) and Synchrotron Light Research Institute (SLRI). It is an intermediate‐energy X‐ray absorption spectroscopy (XAS) beamline at SLRI. The beamline delivers an unfocused monochromatic X‐ray beam of tunable photon energy (1.25–10 keV). The maximum normal incident beam size is 13 mm (width) × 1 mm (height) with a photon flux of 3 × 10 8 to 2 × 10 10 photons s −1 (100 mA) −1 varying across photon energies. Details of the beamline and XAS instrumentation are described. To demonstrate the beamline performance, K ‐edge XANES spectra of MgO, Al 2 O 3 , S 8 , FeS, FeSO 4 , Cu, Cu 2 O and CuO, and EXAFS spectra of Cu and CuO are presented.
