The Trigger Menu Handler of the ATLAS Level-1 Central Trigger Processor
The role of the Central Trigger Processor (CTP) in the ATLAS Level-1 trigger is to combine information from the calorimeter and muon trigger processors, as well as from other sources, e.g. calibration, and to make the final Level-1 decision. The information sent to the CTP consists of multiplicity values for a variety of (electron, gamma, tau/hadron and jet) transverse-momentum thresholds, and ...
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 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 ...
متن کاملA Demonstrator for the ATLAS Level-1 Muon to Central Trigger Processor Interface (MUCTPI)
The Level-1 Muon Trigger Interface (MUCTPI) to the Central Trigger Processor (CTP) receives trigger information from the detector-specific logic of the muon trigger. This information contains up to two muon-track candidates per sector. The MUCTPI combines the information of all sectors and calculates total multiplicity values for each of six programmable pT thresholds. It avoids double counting...
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 ...
