Kurzfassung
ATLAS is one of two general purpose detectors at the world’s largest particle accelerator, the Large Hadron Collider (LHC), and has been designed to study proton-proton collisions at a center of mass energy sqrt(s)= 14 TeV. While the LHC is currently operating at sqrt(s) = 7 TeV, it collided proton beams at sqrt(s) = 900 GeV and sqrt(s) = 2.36 TeV between November 23 – December 16, 2009. ATLAS has an innermost charged particle precision tracking system for measurement of the trajectories of the charged particles emerging out of collisions. To achieve its physics goals the alignment of the tracking detector elements should be known to a precision of a few to few tenths microns. However, due to the large number of position sensitive devices, this constitutes a major challenge. This note presents the alignment approach and the results using the data collected from cosmic-rays and proton-proton collisions at sqrt(s) = 900 GeV.
