Description

In view of the Long Shutdown 3 the ALICE experiment is foreseeing an upgrade of the inner barrel of its Inner Tracking System (ITS3), based on Monolithic Active Pixel Sensors produced in a commercial 65 nm CMOS technology. This technology represents the baseline for the development of tracking systems for future experiments at colliders (NA60+, EPIC@EIC, ALICE 3, FCC…).
ALICE 3 experiment has been proposed as a next generation heavy-ion experiment for the HL era of the LHC. The tracking system will be based on a vertex detector, integrated in a retractable structure inside the beam pipe to achieve the best possible pointing resolution, and a very-large-area outer tracker, surrounding the vertex detector. Furthermore, a Time Of Flight (TOF) system, equipped with silicon sensors with a timing resolution of 20 ps, will be of crucial importance to identify charged particles.
The “MAPS” group of INFN Torino is deeply involved in the R&D of monolithic sensors, with and without timing capabilities, for the projects mentioned above.
In this contribution the present status of the R&D will be presented, highlighting the detector requirements, sensor specifications together with the results from the latest test beam.
