Abstract

The ATLAS trigger system is a crucial component of the ATLAS experiment at the LHC.It is responsible for selecting events in line with the ATLAS physics programme. This paper presentsan overview of the changes to the trigger and data acquisition system during the second longshutdown of the LHC,and shows the performance of the trigger system and its components in the proton-proton collisionsduring the 2022 commissioning period as well as its expected performance inproton-proton and heavy-ion collisions for the remainder of the third LHC data-taking period (2022–2025).
