The Micro-Vertex-Detector of the PANDA Experiment — •Tobias Stockmanns — Forschungszentrum Jülich GmbH, Institut für Kernphysik 1, 52425 Jülich

The Micro-Vertex-Detector (MVD) is the key component of the PANDA experiment to identify open charm and strangeness by detecting secondary decays of particles displaced from the primary interaction point. These decay lengths vary from a few 100 micro meter for charmed mesons and baryons up to several cm for strange hadrons. In addition, the MVD significantly improves the momentum resolution of the large volume central tracker.

The MVD is made of silicon strip and pixel detectors with more than 10 million readout channels. With the necessity of a continuous untriggered readout and the highest requirements for spatial resolution and material budget the MVD is one of the most demanding detectors within PANDA.

End of last year the TDR of the MVD was successfully completed. The outcome of the intense R&D project and the results of a detailed detector simulation program will be presented in this talk.
