Status of the CBM Micro Vertex Detector* — •Michael Deveaux — Institut für Kernphysik, Goethe Universität Frankfurt am Main

The CBM-Experiment will study the phase diagram of hadronic matter in the region of highest baryonic densities. For a first time in this energy regime, the hot and dense fireball will be investigated with a broad set of probes, among them open charm. Separating those rare particles from the rich background formed in the 10-40 AGeV heavy ion collisions calls for a micro vertex detector (MVD) with a unprecedented performance in terms of spatial resolution (few µm), low material budget ( 0.3 X₀), high radiation hardness and outstanding rate capability.

We will show the concept of this detector, which will presumably base on CMOS-Monolithic Active Pixel Sensors, and discuss our achievements in the fields of detector integration and sensor R&D.
