SUT-NANOTEC-SLRI beamline for X-ray absorption spectroscopy

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 (1.25-10keV). The maximum normal incident beam size is 13mm (width) x 1mm (height) with a photon flux of 3 x 10(8) to 2 x 10(10)photons s(-1) (100mA)(-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, Al2O3, S-8, FeS, FeSO4, Cu, Cu2O and CuO, and EXAFS spectra of Cu and CuOare presented.
