International Conference on X-ray Absorption Fine Structure, XAFS16, Meeting locationKarlsruhe, Germany, 23 Aug 2015 - 28 Aug 2015   X-ray absorption spectroscopy on dilute samples is still a challenge nowadays. By means of the fluorescence processes that follow the absorption it is possible to obtain the XAS spectrum; however, in order to gain sufficient statistics a multi-pixel fluorescence detector is required.
