What is High-Luminosity ATLAS?

The High-Luminosity phase of the Large Hadron Collider (HL-LHC), set to begin in 2030, will deliver roughly an order of magnitude more data than previous runs. This unprecedented dataset will enable precision measurements of the Higgs boson’s properties and enhance sensitivity to a wide range of new-physics scenarios. To study this wealth of data, the ATLAS Collaboration is undertaking major detector upgrades that incorporate state-of-the-art technologies. HL-ATLAS will include a completely new inner tracker, a high-granularity silicon timing detector, and enhancements to the trigger and data-acquisition systems.
