The variation with Einc in the detector quantum efficiency of PILATUS detectors with silicon sensor material of different thicknesses (Donath et al., 2013). The theoretical quantum efficiencies are the fraction of incident radiation that is calculated to be absorbed in the sensitive volume of the silicon sensor using mass attenuation coefficients from the NIST XCOM tables (Berger et al., 1998). The falls in quantum efficiency at 1.839 keV and 1.560 keV are as a result of the silicon K- and LI-absorption-edges, respectively. |
