During the shutdown of CERN Large Hadron Collider in 2013-2014, an additional pixel layer was installed between existing Pixel detector ATLAS experiment and a new, smaller radius beam pipe. The motivation for this new layer, Insertable B-Layer (IBL), to maintain or improve robustness performance tracking system, given higher instantaneous integrated luminosities realised following shutdown. Because extreme radiation collision rate environment, several radiation-tolerant sensor electronic...

The increase of the particle flux at HL-LHC with instantaneous luminosities up to L=7.5 × 10 34 cm −2 s −1 will have a severe impact on ATLAS detector reconstruction and trigger performance. end-cap forward region where liquid Argon calorimeter has coarser granularity inner tracker poorer momentum resolution be particularly affected. A High Granularity Timing Detector installed in front calorimeters help charged-particle luminosity measurement. This low angle is introduced augment new...

In 2004 at the ATLAS (A Toroidal LHC ApparatuS) combined test beam, one slice of barrel detector (including an Inner Detector set-up and Liquid Argon calorimeter) was exposed to particles from H8 SPS beam line CERN. It first occasion electron performance ATLAS. This paper presents results obtained for momentum measurement p with LAr calorimeter (energy E linearity resolution) in presence a magnetic field momenta ranging 20 GeV/c 100 GeV/c. Furthermore particle identification capabilities...
