Proton-proton collisions at s = 7 TeV and heavy ion collisions at √sNN = 2.76 TeV were produced by the LHC and recorded using the ATLAS experiment’s trigger system in 2010. The LHC is designed with a maximum bunch crossing rate of 40 MHz and the ATLAS trigger sys- tem is designed to record approximately 200 of these per second. The trigger system selects events by rapidly iden- tifying signatures of muon, electron, photon, tau lepton, jet, and B meson candidates, as well as using global event signa- tures, such as missing transverse energy. An overview of the ATLAS trigger system, the evolution of the system during 2010 and the performance of the trigger system components and selections based on the 2010 collision data are shown. A brief outline of plans for the trigger system in 2011 is pre- sented.
