Abstract :
The fluorescence X-ray scanning 2D microprobe based on a Bragg-Fresnel multilayer lens (BFML) has been tested at the ESRF, Grenoble (France) for the first time. A single elliptical BFML has been used for two-dimensional focusing of the X-ray synchrotron beam of an undulator source in the energy range of 12 keV. A spatial resolution of 2.4 μm and a photon intensity of about 1010 photons per second have been measured using a Cr knife-edge test object.
