Commissioning of the ATLAS Inner Tracking Detectors
The ATLAS experiment is described in [1]. The Transition Radiation Tracker (TRT), the Semiconductor Tracker (SCT) and the Pixel detector must provide track identification for η (η = −ln(tg( θ2 )), where θ is the polar angle defined wrt the z axis, along the beam) lower than 2.5 and transverse momentum greater than 500 MeV, with a momentum resolution of σPT PT = 0.05%PT ⊕ 1%. A good vertex recon...
متن کاملATLAS Inner Tracker Performance at the beginning of the LHC Run - 2 . ∗
The ATLAS experiment performs studies of proton-proton collisions at the Large Hadron Collider (LHC) at CERN. The Inner Detector is a part of the ATLAS apparatus placed nearest the interaction point, designed to measure charged particles momenta and their trajectories, and to reconstruct vertices of decays of physics objects created in collisions. During the LHC technical stop 2013-2015, the In...
متن کاملPerformance of the ATLAS Muon Trigger in Run I and Upgrades for Run II
The ATLAS experiment at the Large Hadron Collider (LHC) has taken data at a centre-of-mass energy between 900 GeV and 8 TeV during Run I (2009-2013). The LHC delivered an integrated luminosity of about 20 fb−1 in 2012, which required dedicated strategies to ensure the highest possible physics output while effectively reducing the event rate. The Muon High Level Trigger has successfully adapted ...
متن کاملThe ATLAS detector: status and performance in Run-II
During the first extended shutdown of the LHC, in 2013 and 2014, the ATLAS detector has undergone several improvements. A new silicon pixel detector layer has been added inside of the existing layers, enhancing vertex identification, while the coverage of the muon detector has been significantly expanded. Many other detector systems have been upgraded to handle the higher expected pileup condit...
متن کاملPreparing ATLAS reconstruction software for LHC ' s Run 2
In order to maximize the physics potential of the ATLAS experiment during LHC’s Run 2, the reconstruction software has been updated. Flat computing budgets required a factor of three improved execution time, while the new xAOD data format forced changes in the reconstruction algorithms. Physics performance was also made better. This paper presents an overview of the improvements made to the rec...
