The initial interactions rate foreseen at LHC at the designed luminosity of 1034 cm-2 s-1 is 1 GHz. Such an extremely large rate must be reduced by the trigger system to 100 Hz in order to allow permanent data storage preserving the much less probable physics signals against a large background. The ATLAS Level-1 muon trigger will be crucial for the online selection of events with high transverse momentum...
The three-level ATLAS trigger system has been designed to reduce the initial LHC interactions rate from 1 GHz, to ~100 Hz in order to allow permanent data storage. This result must be achieved preserving the less probable physics signals against a large background therefore providing a challenge task for the trigger and DAQ system. The level-1 muon trigger in the barrel region of the muon spectrometer...
