Abstract
We examine the high count-rate performance of an energy-resolving detector in the three operating modes of the Advanced Photon Source (APS). Specifically, we present the optimal dead-time corrections for the SII Vortex silicon drift diode (SDD) detector using a digital pulse processor, highlighting the differences in operation between the 24-bunch, 324-bunch, and hybrid singlet modes of the APS. We analyze the input count rate (ICR), output count rate (OCR), and several regions of interest (ROIs). We find that the correct formula for dead-time correction can extend the use of the detector to significantly higher count rates.
