Alignment of the ATLAS inner detector tracking system

Abstract

ATLAS is a general-purpose experiment designed to study the high-energy collisions produced by the Large Hadron Collider. It is equipped with a sophisticated tracking system, which will reconstruct the tracks of charged particles and determine their production and decay vertices. Accurate alignment of this tracking system is necessary for ATLAS to achieve its physics goals. The methods used to achieve alignment are discussed and results from both Monte Carlo studies and cosmic data are presented.
