Development of the multicell SDD for Elettra and SESAME XAFS beamlines

We report on the first tests of a new prototype fluorescence detector in development for the XAFS beamlines at Elettra (Trieste, Italy) and SESAME (Amman, Jordan) synchrotrons. The beamlines operate in the energy ranges 2–27keV and 4–30keV, respectively. The new detector system is based on Silicon Drift Detector (SDD) and SIRIO ultra-low–noise front-end ASIC. The custom-made detector, front-end and back-end electronics system are designed specifically on the beamlines requirements and developed within the framework of the INFN ReDSoX collaboration. The SDD sensors are produced in collaboration with FBK
