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 to 2 × 10 photons s (100 mA) varying across photon energies. Details of the beamline and XAS instrumentation are described. To demonstrate the beamline performance, K-edge XANES spectra of MgO, AlO, S, FeS, FeSO, Cu, CuO and CuO, and EXAFS spectra of Cu and CuO are presented.
SUT-NANOTEC-SLRI光束线于2012年建成，是由泰国苏兰拉里理工大学（SUT）、国家纳米技术中心（NANOTEC）和同步辐射光研究所（SLRI）共同建立的同步辐射利用联合研究设施的旗舰项目。它是SLRI的一条中能X射线吸收光谱（XAS）光束线。该光束线提供一束光子能量可调（1.25 - 10 keV）的非聚焦单色X射线束。最大正入射光束尺寸为13毫米（宽）×1毫米（高），光子通量在3×10至2×10光子/秒（100毫安）之间，随光子能量变化。文中描述了光束线和XAS仪器的详细信息。为展示光束线性能，给出了MgO、AlO、S、FeS、FeSO、Cu、CuO和CuO的K边XANES光谱，以及Cu和CuO的EXAFS光谱。
