The 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 ...
متن کاملPrototype Readout Module for the ATLAS Level-1 Calorimeter Trigger Processors
The level-1 calorimeter trigger consists of three subsystems, namely the Preprocessor, electron/photon and tau/hadron Cluster Processor (CP), and Jet/Energy-sum Processor (JEP). The CP and JEP will receive digitised calorimeter trigger-tower data from the Preprocessor and will provide trigger multiplicity information to the Central Trigger Processor and region-of-interest (RoI) information for ...
متن کاملThe performance of a Pre-Processor Multi-Chip Module for the ATLAS Level-1 Trigger
We have built and tested a mixed signal Multi-Chip Module (MCM) to be used in the Pre-Processor of the ATLAS Level-1 Calorimeter Trigger. The MCM performs high speed digital signal processing on four analogue trigger input signals. Results are transmitted serially at a serial data rate of 800 MBd. Nine chips of different technologies are mounted on a four layer copper substrate. Analogue-to-dig...
متن کاملTests of the CMS Level-1 Regional Calorimeter Trigger Prototypes
The CMS calorimeter regional trigger system is designed to detect signatures of isolated and non-isolated electrons/photons, jets, τs, and missing and total transverse energy using deadtimeless pipelined architecture. This system comprises of 18 crates of custom-built electronics. The pre-production prototype backplane, boards, links and ASICs have been built and their performance is characteri...
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...
