Beamline BL14W1 specializes in x-ray absorption fine structure (XAFS). It has been open for users since May 2009. It is tunable by two types of double crystal monochromator for covering photon energy from 4.5 keV to 50 keV. K-edge absorption of Titanium up to Lanthanum can be studies. Other heavier atomic species can be investigated via L edges. The bulk of our scientific program is in catalysis, materials science and environmental research.
