Allpix squared simulations of multi-element germanium detectors for synchrotron applications

Abstract X-rays spectroscopy experiments at synchrotron facilities were limited for many years by the maximum input count rate and signal-to-background ratio of germanium fluorescence detectors. These limitations are related to semiconductor device, sensor configuration its response incident X-ray flux different energies. In order understand quantify such limitations, physics simulation detector is a powerful tool provide guidelines designing, prototyping improving detectors, as well modelling experimental environments, which reduces time cost development. For this purpose, first complete operational chain based on Allpix Squared framework presented, customized multi-element detectors combined with three-dimensional simulations electric field weighting potential, COMSOL Multiphysics®. Based chain, quantification charge sharing effect beam energies has been made equipped without collimator. addition, two measurements have performed SAMBA beamline SOLEIL synchrotron. The data used set up full good agreements observed between simulation.
