 The tuneable X-ray beam, coupled with the high resolving power of the crystal monochromators and with the motorised stages for sample and detectors movement, offers the synergistic application of XRF, XRR, and XAFS techniques in several geometries. The beamline operates in the energy range 2 - 14 keV with small spectral bandwidth (Si(111), InSb crystals) or in the 0.7 - 14 keV with high flux (multilayers).
