A Fluorescence Detector System for XAFS (X-ray Absorption Fine Structure) composed of 8 monolithic arrays of SDDs (Silicon Drift Detector), each having 8 cells of 9 mm${}^{2}$ area, is being realized within the INFN ReDSoX Collaboration. It will be used for X-ray absorption spectroscopy at the Jordan's synchrotron light source SESAME that provides a photon beam with an energy range between 3 and 30 keV. Detailed characterization tests at ELETTRA Sincrotrone Trieste have demonstrated an energy resolution at the Mn 5.9 keV K$\alpha$ line, for the monolithic array, below 150 eV FWHM at $10^{\circ}$C.
