Abstract
This 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.
