    摘要: The x-ray beamline BL07A, fascinating over the use of the x-rays generated from a 3.1 Tesla, in-achromatic superconducting wiggler at the NSRRC, is designed for x- ray scattering and x-ray absorption spectroscopy for advanced materials researches in the photon energy range 5-23 keV. The beamline optics is optimized over the sequence of the collimating mirror, the double crystal monochromator, the focusing mirror and the higher harmonic rejection mirror. The beamline exhibits substantially identical performances with the ray-tracing simulation, of photon flux 10^13 photons/s with energy resolution △E/E ~ 2 × 10^(−4), focal size 250 μm × 550 μm (vertical × horizontal, FWHM), and higher-harmonic rejection ratio ~ 10^(−4). Three experimental stations, namely, a diffraction/scattering station equipped with eight-circle diffractometer, an EXAFS station, and a micron beam station, all are located in the experimental hutch, upon which, a wide variety of sample environments, including temperature, pressure, electric field, and magnetic field, greatly extend the capabilities of detection in the extreme and non- ambient conditions.
