The ALICE collaboration is currently developing a new vertex detector ("ITS3"), foreseen to be installed in 2026 - 2028 during LHC long shutdown 3 to replace the three innermost layers (Inner Barrel) of the current Inner Tracking System as from Run 4 onwards. ITS3 comprises the use of ultra-thin (down to 50 micrometers) silicon wafers and stitching technologies in 65nm CMOS imaging process to...

In the LHC long shutdown 3, the ALICE experiment upgrades the inner layers of its Inner Tracker System with three layers of wafer-scale stitched sensors bent around the beam pipe. Two stitched sensor evaluation structures, the MOnolithic Stitched Sensor (MOSS) and MOnolithic Stitched Sensor with Timing (MOST) allow the study of yield dependence on circuit density, power supply segmentation,...

Monolithic active pixel sensors (MAPS) are attractive candidates for the next generation of vertex and tracking detectors for future lepton colliders. Especially an only recently accessible 65 nm CMOS imaging technology, that allows for higher logic density at lower power consumption compared to currently used imaging processes, is of high interest. Intensive simulation and characterisation of...
