Abstract :
[en] An energy dispersive X-ray fluorescence instrument has been developed to be used for space exploration. In particular, the electronic readout has been redesigned to withstand the radiation environment of space and improve the energy resolution down to 121.17 eV using an Silicon Drift Detector (SDD). Besides, the instrument uses pyroelectric sources as excitation sources. We include a renormalization to reduce measurement fluctuation from 25.2% to 3.7%. A peak search algorithm has been implemented based on calibration to improve accuracy and reduce possible aging drift effects.
