X-ray absorption spectroscopy beamline is a high-performance hard X-ray beam line optimized for X-ray absorption spectroscopy and derivative experimental methods. The basic aim of the this beamline is to build a high universality, high-brightness XAFS experimental system with high versatility and wide energy rangeto provide the users with a reliable, stable and easy-operated platform for X-ray absorption spectroscopy experiment.
This platform has a conventional experimental method of X-ray absorption spectroscopy, with time resolution and spatial resolution. It is capable of detecting micro/surface’s structures. Meanwhile, this beamline also provides the users with various in-suit sample devices and The XRF/XRD/FTIR and mass spectrometry will be combined to get more information of samples. At last , it has been considered the possibilities for the development of other experimental methods and new experimental methods at the time of design.
The designed energy range is 4.8-45keV, the photon flux at the sample is 2×1013phs/s@10keV@200mA.
A 5m long In-air Undulatoris used as the light source, the main optic element of this beamline is a liquid nitrogen cooling monochromator, a fast monochromator is used for time-resolved experiments, and a KB mirror is used for focusing.
The station has been designed to meet the mm2 spot for routine measurement, micro-spot (micron, sub-micron) experimental methods and experimental requirements for comprehensive measurement with XES, HEXPS and other experimental methods in the future.
