Trigger logic of the ATLAS First Level Muon Trigger
We present the design of the first level muon trigger in the central toroid of the ATLAS experiment at the Large Hadron Collider (LHC). The trigger is based on fast, finely segmented gaseous detector, Resistive Plate Chambers (RPC), to unambigously identify the interaction bunch crossing and to provide a sharp threshold over a large interval of transverse momentum. We describe the logic scheme ...
متن کاملThe Level-0 Muon Trigger for the LHCb Experiment
A very compact architecture has been developed for the first level Muon Trigger of the LHCb experiment that processes 40 × 10 proton-proton collisions per second. For each collision, it receives 3.2 kBytes of data and it finds straight tracks within a 1.2 μs latency. The trigger implementation is massively parallel, pipelined and fully synchronous with the LHC clock. It relies on 248 high densi...
متن کاملThe Atlas Muon Trigger Interface (muctpi)
At LHC interesting physics in many cases will be indicated by the presence of muons in an event[1]. Examples are searches for new heavy particles with muons among the decay products. A muon with high pT could indicate such a decay. Another interesting topic to be investigated at LHC is the search for rare B-meson decays. The branching ratio for the decay B0 -> μμ is predicted to be of the order...
متن کاملA first-level calorimeter trigger for the ATLAS experiment
In the RD27 collaboration we have carried out system studies on the implementation of the first level calorimeter trigger processor system for the ATLAS experiment to be mounted at the Large Hadron Collider (LHC) at CERN. These studies suggest that the full system can be contained in six 18SU size crates which will process approximately 4000 electromagnetic and 4000 hadronic trigger cells and p...
متن کاملThe Trigger of the Atlas Experiment
With the high bunch-crossing and interaction rates and potentially large event sizes the experiments at the LHC challenge data acquisition and trigger systems. Within the ATLAS experiment, a multi-level trigger system based on hardware and software is employed to cope with the task of event-rate reduction. This review article gives an overview of the trigger of the ATLAS experiment highlighting...
