Our group contributes significantly to the data acquisition of the ATLAS muon detector. During the construction and commissioning phase and for all the first run of the experiment, we held the coordination of DAQ activities of the muon detector, at the same time coordinating the development and application of the common framework for the detector-specific part of the DAQ software. The current activity includes both the operational aspects (maintenance of the current system and support for runs and detector tests) and the development of new features to improve the stability and efficiency of data taking.
