DESCRIPTION:Speakers: BUTTINGER\, Will (University of Cambridge (GB))\nThe
  ATLAS Level-1 Trigger is the first stage of event selection for the ATLAS
  experiment at the LHC. In order to identify the interesting collisions ev
 ents to be passed on to the next selection stage within a latency of less 
 than 2.5 us\, it is based on custom-built electronics. Signals from the Ca
 lorimeter and Muon Trigger System are combined in the Central Trigger Proc
 essor which processes the overall L1 Accept (L1A) decision. The Level-1 Tr
 igger identifies event features such as missing transverse energy\, candid
 ate electrons\, photons\, jets and muons. This talk will present how the L
 evel-1 Trigger System has performed with increasing LHC luminosity and dis
 cuss problems encountered during operations. We will also give an overview
  of the challenges and plans with respect to the increasingly demanding LH
 C running conditions.\n\nhttp://indico.cern.ch/contributionDisplay.py?cont
