Description
Abstract:
The Transition Radiation Tracker (TRT) of the ATLAS experiment is a tracking drift chamber using tubular drift tubes, together with the Pixel Detector and the Semiconductor Tracker it forms the ATLAS inner tracking system.
An additional feature of the TRT is to identify particles by detecting transition radiation photons which are produced when the particle traverses the detector - depending on its mass and momentum.
In my talk I will present the design of the TRT and will describe its assembly including (sometimes hard) lessons which have been learned during the construction phase.
Since more than two years the TRT is now operating in the ATLAS cavern, successfully recording proton collisions at various energies. I will review the operation of the detector and will discuss the results which have been achieved so far and will compare them to what has been expected from the detector during its conception.
