Abstract
Beamline BL11 at the Saga Light Source (SAGA-LS) is designed for X-ray absorption fine structure (XAFS) experiments in the energy range 2.1-23 keV using a Si(111) double crystal monochrometer. For XAFS experiments, the sample temperature can be controlled in the range of 15-1073 K using a cryostat and furnaces. Besides the transmission measurement mode, we can obtain XAFS spectra in fluorescence measurement mode and conversion electron yield modes. An XAFS measurement system under atmospheric pressure for soft X-rays with energies under 3.5 keV was also installed on this beamline. In addition, we can perform in situ XAFS measurements under toxic and harmful gas atmospheres by using a quick XAFS measurement system.
