Paper Abstract

We report on simulation results for the eROSITA instrument background obtained with Monte-Carlo simulations using the Geant4 toolkit. Besides a brief introduction to the simulation environment created at our institute, the input particle spectrum and flux as well as the post-simulation event treatment and analysis are explained. Latest results for the background level and spectral shape induced by interactions of cosmic-ray protons with the camera housing are given. In addition, we show results from different studies concerning variation of the background level as a function of the CCD thickness and the composition of the graded shield.
