A configuration system for the ATLAS trigger
نویسنده
چکیده
The ATLAS detector at CERN’s Large Hadron Collider will be exposed to protonproton collisions from beams crossing at 40 MHz that have to be reduced to the few hundreds of Hz allowed by the storage systems. A three-level trigger system has been designed to achieve this goal. We describe the configuration system under construction for the ATLAS trigger chain. It provides the trigger system with all the parameters required for decision taking and to record its history. The same system configures the event reconstruction, Monte Carlo simulation and data analysis, and provides tools for accessing and manipulating the configuration data in all contexts.

Configuration of the ATLAS Trigger System
In this paper a conceptual overview is given of the software foreseen to configure the ATLAS trigger system. Two functional software prototypes have been developed to configure the ATLAS Level-1 emulation and the High-Level Trigger software. Emphasis has been put so far on following a consistent approach between the two trigger systems and on addressing their requirements, taking into account t...
متن کاملThe ATLAS Trigger Core Configuration and Execution System in Light of the ATLAS Upgrade for LHC Run 2
During the 2013/14 shutdown of the Large Hadron Collider (LHC) the ATLAS first level trigger (L1) and the data acquisition system (DAQ) were substantially upgraded to cope with the increase in luminosity and collision multiplicity, expected to be delivered by the LHC in 2015. Upgrades were performed at both the L1 stage and the single combined subsequent high level trigger (HLT) stage that has ...

The ATLAS detector at CERN's Large Hadron Collider will be exposed to proton-proton collisions from beams crossing at 40 MHz that have to be reduced to the few 100 Hz allowed by the storage systems. A three-level trigger system has been designed to achieve this goal. We describe the configuration system under construction for the ATLAS trigger chain. It provides the trigger system with all the ...
متن کاملSoftware Framework Developed for the Slice Test of the ATLAS Endcap Muon Trigger System
A sliced system test of the ATLAS end cap muon level 1 trigger system has been done in 2001 and 2002 separately. We have developed an own software framework for property and run controls for the slice test in 2001. The system is described in C++ throughout. The multi-PC control system is accomplished using the CORBA system. We have then restructured the software system on top of the ATLAS onlin...
متن کاملReadiness of the ATLAS Trigger and Data Acquisition system for the first LHC beams
The ATLAS Trigger and Data Acquisition (TDAQ) system is based on O(2k) processing nodes, interconnected by a multi-layer Gigabit network, and consists of a combination of custom electronics and commercial products. In its final configuration, O(20k) applications will provide the needed capabilities in terms of event selection, data flow, local storage and data monitoring. In preparation for the...
