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

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 *m 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. To achieve the required resolution and to be operational in a harsh radiation environment the MVD is made of position sensitive silicon pixel and strip detectors, which are arranged in four barrel layers and six disk layers around the interaction point of the anti-proton beam and the target material. The total size of the MVD is 40 cm in length and 30 cm in diameter. With more than 10 million readout channels, a continuous untriggered readout and the highest requirements for spatial resolution and material budget within PANDA, the MVD faces many technological challenges. The presentation includes all technical aspects necessary to construct such a complex detector, starting from the physical requirements, the necessary simulation steps up to the first prototypes of subcomponents.
