Abstract

ATLAS [1] is one of the general purpose detectors observing proton-proton collisions provided by the LHC [2] at CERN. The ATLAS Trigger and Data Acquisition (TDAQ) system [3] is responsible for conveying the event data from the detector up to a permanent mass-storage system provided by CERN. This work focuses on the Data Logger system which lies at the end of the data flow path in the TDAQ system. The Data Logger is a transient storage system recording the selected event data on hard drives before transferring them to permanent storage where they are available for offline analysis.
