LHCb Level-0 Trigger Detectors
The calorimeter and muon systems are essential components to provide a trigger for the LHCb experiment. The calorimeter system comprises a scintillating pad detector and pre-shower, followed by electromagnetic and hadronic calorimeters. The calorimeter system allows photons, electrons and hadrons to be identified, and their energy to bemeasured. Themuon system consists of five measuring station...
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 high level trigger for rare decays at LHCb
The LHCb experiment is dedicated to the study of CP violation and rare B decays. A trigger system is developed to filter these decays from the LHC background environment. An overview of the LHCb trigger strategy is given in this paper as well as an illustration on how the trigger selects the rare decays B d → K * 0 + − and B s → and their control samples, which are used to parametrize possible ...
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...
متن کاملThe ATLAS Level - 1 Calorimeter Trigger Pre - Processor
At the input to the calorimeter part of the Level-1 Trigger a Pre-Processor system performs the preprocessing of about 7200 analogue trigger-tower signals. The preprocessing includes digitisation, identi cation of the corresponding bunch-crossing in time (BCID), calibration of the transverse energy, rate monitoring, readout of raw trigger data, and high-speed data transmission to the following ...
