Status of the MIMOSIS sensor for the CBM Micro Vertex Detector* — •Benedict Arnoldi-Meadows for the CBM-MVD collaboration — Goethe-Universität Frankfurt

The CMOS Monolithic Active Pixel Sensor (MAPS) MIMOSIS will be used as the sensor of the Micro Vertex Detector (MVD) of the CBM experiment, which is foreseen to receive beam on target in 2028. The sensor is currently being developed by IPHC Strasbourg in cooperation with University Frankfurt and GSI, with the MIMOSIS-2.1 sensor being its latest and last prototype.

Both in-beam performance studies validating changes in the sensor, and studies related to the selection, preparation, and operation of suitable sensors in the experiment have been conducted with MIMOSIS-2.1 prototype sensors. This contribution will present the recent progress made towards the final sensor for the experiment.

*This work has been supported by BMFTR (05H24RF5), GSI, Eurizon, HGS-HIRe, and HFHF.
