Traditional XAFS spectrum is obtained by controlling the rotation of the monochromator by a stepper driver, then measuring the absorption coefficient of each energy point. While in quick-scanning XAFS (QXAFS), the angle of the monochromator moves continuously and quickly, greatly reducing the spectral acquisition time. It has become a powerful tool to study in-situ dynamic processes. Currently QXAFS is mainly used in hard X-ray absorption spectroscopy beamlines of synchrotron radiation facilities, here we have developed a QXAFS system in the medium-energy X-ray beamlines, which will improve the function of XAFS beamlines and extend their capabilities to a wider user community.
