Resumen:
Proton-proton collisions at sqrt{s} = 7 TeV and heavy ion collisions at
sqrt{s_NN} = 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 system is
designed to record approximately 200 of these per second. The trigger
system selects events by rapidly identifying signatures of muon,
electron, photon, tau lepton, jet, and B meson candidates, as well as
using global event signatures, 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 presented
