Particle detectors based on Monolithic Active Pixel Sensors (MAPS) provide the basis for the next generation of vertex detectors with ultra low material budget and truly cylindrical geometry. Arrays of sensor elements stitched into wafer-scale and curved in a barrel geometry serve as the next upgrade of the inner tracking system (ITS3) of the ALICE experiment at CERN. A test environment hosting six bent sensors in the uITS3 geometry and their read out synchronized with CsI scintillator crystals has been recently employed in the test beam experiment at the Bronowice Cyclotron Facility (CCB) in Poland.
In this talk, the sensors technique, the experimental setup and preliminary results of the CCB experiment will be discussed.
