| Abstract | The Liquid Argon calorimeter of the ATLAS detector provides inputs to the first level of the ATLAS trigger. After the successful period of data-taking during the second run of the LHC (Run-2) the ATLAS detector entered into a long period of shutdown. In 2022 the LHC has started a new data taking period Run-3. During the Run-3 period (2022 2025), it expects to have higher luminosity than Run-2 with pile-up of up to 80 interactions per bunch crossing.To cope with these harsh conditions, a new trigger readout system has been installed during the long shutdown. The new system should improve the triggering performances for electromagnetic objects significantly. This will be achieved by increasing the granularity of the readout system available at triggerlevel by up to a factor of ten. This new trigger system is currently undergoing commissioning in order to become the main LAr trigger readout in 2023.This contribution will present the current status of the Liquide Argon Calorimeter system and the commissioning to be completed towards the full operation of the new trigger readout system for Run-3 of the LHC. |
