The CAD model of the PANDA Micro-Vertex-Detector in physics simulations

The Micro-Vertex-Detector (MVD) constitutes the inner tracker of the PANDA experiment, one of the large installations at the forthcoming FAIR facility. An optimization of the overall design has been accomplished. Currently the project is making rapid progress in hardware developments towards a finalized technical solution for the detector assembly. Therefore, suited tools are necessary to validate the impact of engineering solutions on the physics performance and to introduce a more realistic description of the detector. The cross-link between engineering developments and detector simulations is important for both further optimization of the detector assembly and appropriate implementation of the MVD into the PANDA simulation framework. s article, a full chain of the migration of a detailed CAD model including all technical and engineering input to the software framework used for detector simulations and future data analysis of the PANDA experiment is presented. First, a short introduction to the experiment and a description of the conceptual layout is given. Afterward, the detailed MVD model and introduction to the physics simulation framework are described. Finally, first results of coverage tests performed and radiation length studies are exemplarily presented in order to demonstrate the successful migration of the entire detector model.
