Description
While the on-going Run-3 data-taking campaign will provide twice the integrated proton-proton luminosity currently available at the Large Hadron Collider (LHC), most of the data expected for the full LHC physics program will only be delivered during the High Luminosity LHC phase, currently scheduled to start in 2030. For this, the LHC will undergo an ambitious upgrade program to be able to deliver an instantaneous luminosity of 7.5 × 10^34 cm−2 s−1, allowing the collection of more than 3 ab−1 of data at √s =13.6 (14) TeV. This unprecedented data sample will allow ATLAS to perform several precision measurements to constrain the Standard Model (SM) Theory in yet unexplored phase-spaces, in particular in the Higgs sector, a phase-space only accessible at the LHC. To benefit from such a rich data-sample it is fundamental to upgrade the detector to cope with the challenging experimental conditions that include huge levels of radiation and pile-up events. The ATLAS upgrade comprises the completely novel all-silicon Inner Tracker (ITk) with extended rapidity coverage that will replace the current Inner Detector; a redesigned trigger and data acquisition system for the calorimeters and muon systems allowing the implementation of a free-running readout system. This presentation will describe the ongoing ATLAS detector upgrade status and the main results obtained with the prototypes, giving a synthetic, yet global, view of the whole upgrade project. The focus will be on the Canadian contributions to the tracking and calorimeter upgrades which are in progress.
