Detection Performance of MIMOSIS-1, a CMOS Sensor Prototype Developed for the CBM-MVD

<!--HTML-->The Micro-Vertex Detector of the CBM experiment at FAIR/GSI requires very light detector stations equipped with highly granular and thin pixel sensors adapted to hostile running conditions. A specific CMOS pixel sensor, called MIMOSIS, is being developed for this purpose. Inspired by the ALPIDE sensor equipping the ALICE ITS, its design is adapted to higher hit rate and radiation tolerance. The first full scale prototype was fabricated in 2020 with several epitaxial layer variants. The chips were assembled in a beam telescope which was operated at DESY. First results of the signal-to-noise and detection performance evaluations will be presented.
