Seminario generale INFN

Between 2024 and 2026, the LHC at CERN will be upgraded to become the High-Luminosity LHC (HL-LHC). It will deliver proton-proton collisions at a higher energy and instantaneous luminosity than will have been achieved before. While this will benefit both new physics searches and precision measurements, it will also introduce new challenges for ensuring excellent detector performance.
To cope with these challenges, the current ATLAS Inner Detector (ID) will be replaced with a new Inner Tracker (ITk). The ITk will have greater angular acceptance than the ID, (|eta|<4, compared to |eta|<2.5), and better-or-equal performance than the ID. It is expected to collect roughly 13 times more data than the ID will do in its lifetime. However, it will also need to withstand 13 times more radiation damage than the ID as a result, while still retaining excellent performance.
In this seminar, the fundamentals of tracking detector performance will be examined, considerations for the design of the ITk will be discussed, as will the design process, and physics analysis prospects will be reviewed. The seminar is aimed at a general physics audience: suitable for keen physics students and academics alike.
