Abstract

Abstract:

The BL14W1 beamline at Shanghai Synchrotron Radiation Facility (SSRF) is an X-ray absorption finestructure (XAFS) beamline, for investigating atomic local structure, which is demanded extensively in the fields of physics, chemistry, materials science, environmental science and so on. The beamline is based on a 38-pole wiggler with the maximum magnetic field of 1.2 T. X-rays of 4.5–40 keV can be extracted by the optical scheme consisting of white beam vertical collimating mirror, liquid-nitrogen-cooled double crystal monochromator of Si(111) and Si(311), toroidal focusing mirror and higher harmonics rejection mirror. The maximum photon flux about 5× 10¹² photons/s at the sample at 10 keV, with a beam size of 0.3mm × 0.3 mm. The beamline is equipped with four types of detectors for experiments in either transmission or fluorescence mode. At present, quick-XAFS, grazing incidence XAFS, X-ray emission spectroscopy, high-pressure XAFS and time-resolved X-ray excited optical luminescence methods have been developed.
