The ATLAS Collaboration
We present a study on the performance of the ATLAS jet trigger using pp collision data recorded in April & May 2010 at a center-of-mass energy of 7 TeV. Results are shown for inclusive, dijet, and multijet efficiencies for the Level 1 and High-Level triggers. The Level 1 trigger was used to actively select events for the data analyzed in this note. To test its performance, the High-Level trigger was run on the events selected by Level 1, but not used to actively reject events.
