New X-ray absorption fine structure measurement system under atmospheric pressure in the soft X-ray region at SAGA Light Source

Abstract

A new X-ray absorption fine structure (XAFS) measurement system under atmospheric pressure in the soft X-ray region has been installed at the beamline BL11 of Saga Light Source (SAGA-LS) in Japan. XAFS spectra in the lower photon energy region of about 2–4 keV could be newly obtained at the beamline. The system was applied to obtain sulphur K-edge XAFS spectra of solid and oily specimens using fluorescence yield and electron yield modes. The spectra were successfully collected. We anticipate that this new system will have various applications in environmental and biochemical research.
