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 کاملDISTRIBUTED CONTROL AND MONITORING OF HIGH-LEVEL TRIGGER PROCESSES ON THE LHCb ON-LINE FARM
Hence multiple operation modes of the nodes are foreseen. The ECS is being implemented using the commercial software package PVSS II [2], which complies with the industrial control standard SCADA. The ECS is based on the control framework that has been developed for the four LHC experiments [3], into which the Finite State Machine toolkit SMI++ [4] has been integrated to implement the desired h...
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 کاملLHCb trigger streams optimization
The LHCb experiment stores around 10 collision events per year. A typical physics analysis deals with a final sample of up to 10 events. Event preselection algorithms (lines) are used for data reduction. Since the data are stored in a format that requires sequential access, the lines are grouped into several output file streams, in order to increase the efficiency of user analysis jobs that rea...
