Status of the CBM Micro Vertex Detector* — •Benedict Arnoldi-Meadows for the CBM-MVD collaboration — Goethe-Universität 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 stations, operating in the experiment’s target vacuum. The 0.3−0.5 % X₀ thin stations will be equipped with 50 µm thin, highly granular Monolithic Active Pixel Sensors called MIMOSIS. MIMOSIS 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.

The first full-size prototype MIMOSIS-1 was intensely tested for in-beam performance, radiation tolerance and robustness to Single Event Effects. The results of the tests will be summarized and the implications for the next and final prototype MIMOSIS-2, which has been submitted, will be discussed. Moreover, a status of the efforts with regard to integration and cooling in vacuum towards the final MVD will be given.
