The Compressed Baryonic Matter Experiment (CBM) is one of the core experiments
of the future FAIR facility. It will explore the phase diagram of strongly
interacting matter in the region of high net-baryon densities with numerous
probes including open charm. The Micro Vertex Detector (MVD) will enable
secondary vertex reconstruction with a resolution along the beam axis of 10 – 20
µm, enhance background rejection in dielectron spectroscopy and extend the
capability in the reconstruction of weak decays to channels with a neutral
particle in the final state. The detector comprises up to four stations placed
next to the target in vacuum. The stations are populated with 50~μm thin,
highly-granular customized Monolithic Active Pixel Sensors. A new version called
MIMOSIS, featuring a spatial resolution of <5 μm, a readout speed in the order
of 5 μs as well as radiation tolerance of >10^13 neq/cm² and 3 Mrad is currently
developed at IPHC in Strasbourg.

This contribution will include an update of
the MVD project status and present first physics performance studies using the
new MIMOSIS sensors geometry and performance parameters.
