Abstract: 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.The 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 with a decay length in the order of 100 mu m is essential. Therefore, a special micro-vertex-detector (MVD) is foreseen which allows precise tracking of all charged particles.A hybrid pixel solution was chosen as a baseline concept for the Panda MVD to accommodate the high radiation dose and the required time resolution. To clarify the requirements for the hybrid pixel detector, a Geant4 based simulation was performed using a detector geometry optimized for low radiation length. The design of the detector and the simulation results will be presented in this paper. (c) 2006 Elsevier B.V. All rights reserved.
