Validation of the 65 nm TPSCo CMOS imaging technology for the ALICE ITS3 / Ferrero, C (Polytech. Turin ; INFN, Turin) /ALICE Collaboration
During the next Long Shutdown (LS3) of the LHC, planned for 2026, the innermost three layers of the ALICE Inner Tracking System will be replaced by a new vertex detector composed of curved ultra-thin monolithic silicon sensors. The R&D; initiative on monolithic sensors of the CERN Experimental Physics Department, in cooperation with the ALICE ITS3 upgrade project, prepared the first submission of chip designs in the TPSCo 65 nm technology, called MLR1 (Multi Layer Reticle).

Operation and Performance of the Upgraded ALICE Inner Tracking System / Triolo, Andrea Sofia (CERN) /ALICE Collaboration
The ALICE Experiment underwent a major upgrade during the Long Shutdown 2 of the Large Hadron Collider (LHC), which included the installation of a new Inner Tracking System (ITS2).The ITS2, consisting of a 7-layer, pixel-only tracker with 24,000 Monolithic Active Pixel Sensors(MAPS) and 12.5 billion pixels, represents the largest scale application of the MAPS technology in a high-energy physics experiment to date. It has been successfully commissioned for the LHC Run 3, started in July 2022 with proton–proton collisions at a center of mass energy of 13.6 TeV. [...]

ITS3, the ALICE Vertex Detector for LHC Run 4 / Krizek, Filip (Rez, Nucl. Phys. Inst.) /ALICE Collaboration
During LHC Long Shutdown 3 (2026–2028), the ALICE Collaboration plans to upgrade the innermost layers of the current Inner Tracking System detector (ITS) with a novel vertex detector ITS3. The concept of this new vertex detector is based on ultra-thin ($< 50 \mu$m), wafer-scale (up to about $10 \times 26$ cm$^{2}$ large) Monolithic Active Pixel Sensors (MAPS) that are fabricated using the 65 nm CMOS process.
