Hard X-ray micro-focusing beamline at SSRF

The hard X-ray micro-focusing beamline（BL15U1） of SSRF is dedicated to hard X-ray micro/nanospectrochemical analysis consisting of X-ray fluorescence（XRF）, X-ray absorption spectroscopy（XAS） and X-ray diffraction（XRD） techniques. It is one of the most versatile instruments in hard X-ray microscopy science. Since its commission in 2009, BL15U1 has allocated over 25000 h beamtime for users, and about 700 proposals have been executed. The beamline and the experimental end-station were upgraded for several times to facilitate the users＇ experimental needs and make it more convenient to operate. In this paper, we give a review on the beamline, describing its characteristics, recent technical developments, and a few examples of scientific progresses achieved in recent years on BL15U1.
