Description
The Phase II upgrade of the Large Hadron Collider (LHC) aims to significantly increase the accelerator's instantaneous luminosity. To meet the trigger requirements and withstand the higher radiation levels and ageing of electronics, a new readout system for the ATLAS Tile Calorimeter (TileCal) is being developed. The performance of the new TileCal electronics has been evaluated in multiple test beam campaigns at CERN Super Proton Synchrotron. Key results with data collected between 2021 and 2024 using muon, electron, and hadron beams at various energies and incident angles will be discussed. An overview of these beam test campaigns, detailing the upgrades to the calorimeter electronics, trigger system, and particle identification will be presented.
