Simulation of collision fragments impinging the CBM-MVD* — •Hasan Darwish for the CBM-MVD collaboration — Goethe University Frankfurt am Main

The Micro Vertex Detector (MVD) of the CBM experiment will be located close to the target. Consequently, it will be exposed to a dense flux of charged particles from different origins. With respect to the radiation hardness of the sensor, one major question is whether the CMOS Monolithic Active Pixel Sensors of the MVD will be exposed to harmful impacts of nuclear fragments coming from the target, which can potentially lead to a significant damage. We present studies based on GEANT invoking two different models simulating the production of nuclear fragments from relativistic heavy ion collisions. The simulation results and their impact on the requirements for the MVD will be discussed.
