Status of the CBM Micro Vertex Detector — •Benedikt Gutsche for the CBM-MVD collaboration — Goethe-University Frankfurt, Max-von-Laue-Str. 1, 60438 Frankfurt am Main

The Compressed Baryonic Matter (CBM) Experiment will be a core experiment of the future FAIR facility. Its Micro Vertex Detector (MVD) will be composed of four planes, operating in the experiment*s target vacuum. The 0.3 * 0.5% *0 thin stations will be equipped with 50 μm thin Monolithic Active Pixel Sensors called MIMOSIS. This sensor is being developed by IPHC Strasbourg and will provide a spatial and temporal precision of 5 μm and 5 μs, respectively, with a peak rate capability of 80 MHz/cm2. This contribution will report on the progress made during the last phase of R&D. A TrbNet-based readout system for the MIMOSIS sen- sor was deployed, that aims to be an affordable and portable DAQ solution for probe testing and quality assessment. The second gen- eration and next-to-final full-size sensor prototype MIMOSIS-2, was released and is being characterized. The 3D-model of the MVD was updated to a more detailed version and an improved integration and re-working technique of the sensors onto the carrier made of highly heat-conductive TPG was introduced. Simulations have been done, like for the reconstruction efficiencies while comparing tracking and vertexing geometries.
