Status of the vertex detector program of the CBM experiment at FAIR

The Compressed Baryonic Matter Experiment (CBM) is one of the core experiments of the future FAIR facility (Darmstadt/Germany). The fixed-target experiment will explore the phase diagram of strongly interacting matter in the regime of high net baryon densities with numerous rare probes. The Micro Vertex Detector (MVD) will determine the secondary decay vertex of open charm particles with similar to 50 mu m precision, contribute to the background rejection in dielectron spectroscopy, and help to reconstruct neutral decay products of strange particles by means of missing mass identification. The MVD comprises four stations with 0.3 and 0.5% x/X-0, which are placed between 5 and 20 cm downstream the target and inside vacuum. It will host highly-granular, next-generation Monolithic Active Pixel Sensors, with a spatial precision of 5 mu m, a time resolution of 5 mu s, and a peak rate capability of, similar to 700 kHz/mm(2). Moreover, a tolerance to 3. 10(13) n(eq)/cm(2) and greater than or similar to 3 Mrad are required. In this document, we summarize the status of sensor development, station prototyping, and the detector slow control.
