Abstract

The ATLAS experiment pushes the leading edge of experimental particle physics. Increasingly complex hardware, however, brings increasingly complex problems which manifest themselves not only in the detector, but also within the software which drives the detector. The magnitude of the expected interaction rate, too, adds enormous stress to the detector system and the software trigger. In order to prepare the software for these challenges, various detector quantities are considered which may provide debugging handles and robustness against detector problems arising in the ATLAS calorimeter trigger. The effect of electronics noise suppression on these quantities is studied and a brief study of the software trigger performance is followed by recommendations for the implementation of robustness checks.
