摘要：

The eROSITA (extended Roentgen Survey with an Imaging Telecope Array) instrument on the satellite Spektrum-Roentgen-Gamma will perform an all-sky survey as well as pointed observations in the low and medium X-ray energy regime. The seven PNCCD detectors for this instrument have been developed and manufactured at the Max Planck Institute (MPI) Semiconductor Laboratory. We summarize the characterization of this type of PNCCD regarding the spectral redistribution function in the photon energy range from 100 eV to 11 keV. We present the results of Geant4 simulations compared to our measurements. The observed spectral features and their physical origin inside the detector are explained. An overview on the different contributions to the energy resolution of the detector is given.
