The readout concept of the PANDA Micro-Vertex-Detector — •Tobias Stockmanns, Fabian Hügging, Marius C. Mertens, Andrey Sokolov, and James Ritman for the PANDA collaboration — FZ Jülich GmbH, Institut für Kernphysik I, Jülich

The "AntiProton ANnihilations at DArmstadt" - experiment, PANDA, is one of the main experiments of the "Facility for Antiproton and Ion Research" (FAIR) which replaces and extends the existing GSI-facility at Darmstadt. Primary physics goals include precision spectroscopy of charmonium states, establishment of gluonic excitations, the study of modifications of meson properties in the nuclear medium, and precision gamma-ray spectroscopy of single and double hypernuclei. For many of these physics goals an identification of D-mesons via the detection of a secondary vertex is essential. Therefore, a special micro vertex detector (MVD) is foreseen which allows precise tracking of all charged particles.

One of the major challenges in the development of the MVD is the triggerless readout concept of the PANDA experiment. This requires that all detected hit points in the MVD have to be transmitted to the DAQ-system in the control room without any pre selection and with a minimum of material. The maximum data rate is in the order of 100 Gbit/s. To achieve this goal a readout concept was developed which will be presented in this talk.
