Improvement of a Full Field XRF set-up at Beamline L of HASYLAB

In previous experiments, a FF-XRF set-up had been installed and characterized at Beamline L of HASYLAB. This set-up is similar to the one described by Sasov et al. [1] for a laboratory sources and is based on the camera obscura principle; the sample is excited by a broad primary beam and the X-ray fluorescence image is projected through an Pb pin-hole on a CCD, that allows energy dispersive detection of the fluorescence photons. So the distribution of elements in a sample can be determined simultaneous in the whole sample, without moving it.
