چکیده انگلیسی
The ATLAS Transition Radiation Tracker (TRT) is the outermost of the three sub-systems of the ATLAS Inner Detector at the Large Hadron Collider at CERN. It consists of close to 300000 thin-wall drift tubes (straws) providing â¼30 measurements with position resolution of about 120 μm for charged particle tracks with |η| < 2 and pT > 0.5 GeV. Along with continuous tracking, it provides particle identiï¬cation capability through the detection of transition radiation, X-ray photons generated by high momentum particles in the many polymer ï¬bers or ï¬lms that ï¬ll the spaces between the straws. Custom-built analog and digital electronic read-out are optimized to operate at the LHC design luminosity. In this article, a review of the commissioning and ï¬rst operational experience of the TRT detector will be presented. Emphasis will be given to performance studies based on the reconstruction and analysis of proton-proton collision data collected at the LHC. In addition, the response of the TRT detector to the extremely high track density conditions encountered during the ï¬rst heavy ion LHC collisons will be presented.
