The Compressed Baryonic Matter experiment (CBM) is aiming at the study of dense and hot hadronic matter by means of relativistic heavy ion collisions. One important subsystem of CBM is the Micro-Vertex Detector (MVD) which is intended for detecting open charmed particles by reconstructing their displaced decay vertex. The MVD is located close to the collision point. We expect therefore very high occupancies and data rates due to the high multiplicity environment of the heavy ion collisions.
In the work presented here we simulated the occupancy of the MVD. A focus was laid on the substantial amount of delta-electrons produced in the target of the experiment by the passage of beam particles. Their contribution to the detector occupancy has been investigated with GEANT3 and GCALOR for Au beam ions crossing the Au target material. Moreover, strategies to reduce the number of hits caused by those delta-electrons were evaluated. * supported by BMBF(06FY1731)
