Abstract

The ATLAS barrel level-1 muon trigger system has the following main requirements: coarse measurement and discrimination of the muon transverse momentum PT; bunch crossing identification; fast and coarse tracking to identify tracks in the precision chambers that are related to the muon candidate; 2nd-coordinate measurement with a required resolution of 5-10 mm. Integration tests have been carried out between the various components of the system and in conjuction with the detector, front-end and other general sub-systems of the experiment. Results from test beam measurements have been performed in the CERN H8 test beam area, where production detectors from one full trigger tower have been installed.
