Operation and performance of the ATLAS semiconductor tracker
(Journal of Instrumentation, 2014)
The semiconductor tracker is a silicon microstrip detector forming part of the inner tracking system of the ATLAS experiment at the LHC. The operation and performance of the semiconductor tracker during the first years of ...
Characterisation and mitigation of beam-induced backgrounds observed in the ATLAS detector during the 2011 proton-proton run
(Journal of Instrumentation, 2013)
This paper presents a summary of beam-induced backgrounds observed in the ATLAS detector and discusses methods to tag and remove background contaminated events in data. Trigger-rate based monitoring of beam-related backgrounds ...
Triggers for displaced decays of long-lived neutral particles in the ATLAS detector
(Journal of Instrumentation, 2013)
A set of three dedicated triggers designed to detect long-lived neutral particles decaying throughout the ATLAS detector to a pair of hadronic jets is described. The efficiencies of the triggers for selecting displaced ...
Preparing the hardware of the CMS Electromagnetic Calorimeter control and safety systems for LHC Run 2
(Journal of Instrumentation, 2016)
The Detector Control System of the CMS Electromagnetic Calorimeter has undergone significant improvements during the first LHC Long Shutdown. Based on the experience acquired during the first period of physics data taking ...
Monitoring and data quality assessment of the ATLAS liquid argon calorimeter
(Journal of Instrumentation, 2014)
The liquid argon calorimeter is a key component of the ATLAS detector installed at the CERN Large Hadron Collider. The primary purpose of this calorimeter is the measurement of electron and photon kinematic properties. It ...
Standalone vertex finding in the ATLAS muon spectrometer
(Journal of Instrumentation, 2014)
A dedicated reconstruction algorithm to find decay vertices in the ATLAS muon spectrometer is presented. The algorithm searches the region just upstream of or inside the muon spectrometer volume for multi-particle vertices ...
A neural network clustering algorithm for the ATLAS silicon pixel detector
(Journal of Instrumentation, 2014)
A novel technique to identify and split clusters created by multiple charged particles in the ATLAS pixel detector using a set of artificial neural networks is presented. Such merged clusters are a common feature of tracks ...
Correction of beam-beam effects in luminosity measurement in the forward region at CLIC
(Journal of Instrumentation, 2013)
Procedures for correcting the beam-beam effects in luminosity measurements at CLIC at 3 TeV center-of-mass energy are described and tested using Monte Carlo simulations. The angular counting loss due to the combined ...
The performance of the CMS muon detector in proton-proton collisions at root s=7 TeV at the LHC
(Journal of Instrumentation, 2013)
The performance of all subsystems of the CMS muon detector has been studied by using a sample of proton-proton collision data at root s = 7TeV collected at the LHC in 2010 that corresponds to an integrated luminosity of ...
Energy calibration and resolution of the CMS electromagnetic calorimeter in pp collisions at root s=7 TeV
(Journal of Instrumentation, 2013)
The energy calibration and resolution of the electromagnetic calorimeter (ECAL) of the CMS detector have been determined using proton-proton collision data from LHC operation in 2010 and 2011 at a centre-of-mass energy of ...
