The Forward Feature Extractor for the HL-LHC ATLAS Calorimeter Trigger — •Adrian Alvarez Fernandez, Bruno Bauss, Dennis Layh, Ulrich Schaefer, Stefan Tapprogge, and Christian Kahra — Johannes Gutenberg University (Mainz)

The ATLAS detector will undergo many upgrades to account for the more challenging running conditions of the High Luminosity LHC (HL-LHC). Some of these Phase-II upgrades will be focused on improving the trigger system, a crucial part to deal with the higher data rates and increased pile-up. Phase-I upgrades for Run 3 introduced the Feature EXtractors for a more refined processing of the calorimeter information and to better discriminate between jets, photons, electrons and taus. A Forward Feature EXtractor (fFEX) is being developed for the HL-LHC, which will make use of the full detailed calorimeter granularity in the forward region. It will complement the existing Phase-I systems by providing more flexible algorithms in the regions of |eta|>2.5 for electrons and taus and |eta|>3.2 for jets. The hardware design of the fFEX has been finalized and will be discussed in this presentation, as well as the current state of firmware and algorithmic design.
