DESCRIPTION:Speakers: Emily Anne Smith (CERN)\nThe ATLAS level-1 calorimet
 er trigger is a custom-built hardware system\nthat identifies events conta
 ining calorimeter-based physics objects\,\nincluding electrons\, photons\,
  taus\, jets\, and missing transverse energy.\nIn Run 3\, L1Calo has been 
 upgraded to process higher granularity\ninput data.  The new trigger\, cur
 rently running in parallel with the \nlegacy system\, comprises several FP
 GA-based feature extractor modules\, \nwhich process the new digital infor
 mation from the calorimeters and \nexecute more sophisticated trigger algo
 rithms.  The design of the \nsystem will be presented along with an analys
 is of the improved \nperformance of the upgrade in the increasingly challe
 nging Run-3 \nLHC pile-up environment.\n\nhttps://indico.tlabs.ac.za/event
