BL15U1 is a multitechnique hard X-ray microprobe beamline for the energy range 5-20 keV, combined with micro-X-ray fluorescence (μ-XRF), micro-X-ray absorption (μ-XAS), and micro-X-ray diffraction (μ-XRD). The beamline has opened to user since May, 2009, and it’s being applied for a variety of scientific topics such as materials sciences, life sciences, earth and environmental sciences, and archaeology. Hard x-ray microprobe using K-B mirrors is in operation since opening, with a spatial resolution ~2 μm. A nano-focusing system by using zone-plate is developed also，with a beam size smaller than 200 nm at 10keV.
