Abstract: X-ray Absorption Fine Structure experiments conducted at synchrotron facilities are currentlylimited by the performance of the current generation of Silicon and Germanium detectors. Inorder to mitigate this limitation, the detector consortium of the European project LEAPS-INNOVhas undertaken an ambitious R&D program devoted to develop a new generation of multi-elementmonolithic Germanium detectors for X-ray detection. Two detector prototypes are currently beingdeveloped and are expected to be commissioned end of 2024. After a brief introduction to theproject, the paper will focus on the efforts to evaluate and optimize the performance of theprototypes using a full simulation chain developed within the framework of the LEAPS-INNOVproject. These evaluations demonstrate that by combining a collimator, with cross-talk correctionsand charge sharing rejection in the digital pulse processor, a signal-to-background ratio greaterthan 1000 could be attained in the energy range of interest from 5 keV to 100 keV.
