5 The first - level trigger of ATLAS
Due to the huge interaction rates and the tough experimental environment of pp collisions at a centre-of-mass energy √ s = 14 TeV and luminosities of up to 1034cm−2s−1, one of the experimental challenges at the LHC is the triggering of interesting events. In the ATLAS experiment a three-level trigger system is foreseen for this purpose. The first-level trigger is implemented in custom hardware ...
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 H1 First Level Fast Track Trigger
The HERA collider has recently been upgraded to produce a factor of approximately 5 more luminosity. In parallel, upgrades to the H1 detector and trigger have been necessary. One of the projects was the design of an improved Fast Track Trigger (FTT) which should replace the old track trigger and is based on the central drift chambers of the H1 experiment. This work describes the design and expe...
متن کاملTrigger 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 کاملBunch-Crossing Identification for the ATLAS First-Level Calorimeter Trigger
As part of the design studies for the ATLAS first-level calorimeter trigger, we have been investigating the process of bunchcrossing identification (BCID). Various digital BCID algorithms have been investigated using software simulation. Furthermore, a demonstrator system has been constructed which performs BCID on 36 channels of trigger data. The BCID algorithms are implemented in Field-Progra...
