Item Commissioning, operations and monitoring of the large scale tracking system for the ATLAS experiment(Institute of Nuclear Physics Polish Academy of Sciences, 2017) Stanecka, EwaThis monograph describes the control, operation and performance as- pects of the ATLAS Inner Detector at the Large Hadron Collider at CERN. The Inner Detector is a large system with almost 90 mil- lion readout channels. It combines semiconductor devices (pixels and silicon strip) and straw gaseous detectors to measure trajectories of the charged particles emerging from proton-proton collisions and to reconstruct vertices of the interactions. A specialised Detector Con- trol System designed to allow robust and safe operations of the Inner Detector is described. The details of the environmental management projects as well as the tools for monitoring of the radiation levels inside the Inner Detector volume and protection against beam induced acci- dents are given. The improvements done in the Inner Detector during the long technical stop at the LHC to prepare for proton bunches col- lisions every 25 ns, with the energy √ s =14 TeV and instantaneous luminosity ∼ 1 × 10 34 cm− 2 s− 1 are mentioned. Finally, the combined Inner Detector tracking performance at the beginning of the second season of data taking at LHC is presented.
