Recent aging studies for the ATLAS transition radiation tracker
/ Capéans-Garrido, M ; Åkesson, T ; Anghinolfi, F ; Arik, E ; Baker, O K ; Baron, S ; Benjamin, D ; Bertelsen, H ; Bondarenko, V ; Bychkov, V et al.
The transition radiation tracker (TRT) is one of the three subsystems of the inner detector of the ATLAS experiment. It is designed to operate for 10 yr at the LHC, with integrated charges of similar to 10 C/cm of wire and radiation doses of about 10 Mrad and 2 multiplied by 10**1**4 neutrons/cm**2. [...]

Operation of the ATLAS Transition Radiation Tracker under very high irradiation at the CERN LHC
/ Åkesson, T ; Arik, E ; Baker, K ; Baron, S ; Benjamin, D ; Bertelsen, H ; Bondarenko, V ; Bychkov, V ; Callahan, J ; Capéans-Garrido, M et al.
The ATLAS Transition Radiation Tracker (TRT) performance depends critically on the choice of the active gas and on its properties. The most important operational aspects, which have led to the final choice of the active gas for the operation of the TRT at the LHC design luminosity, are presented. [...]

Status of design and construction of the transition radiation tracker (TRT) for the ATLAS experiment at the LHC
/ Åkesson, T ; Anghinolfi, F ; Arik, E ; Baker, O K ; Baron, S ; Benjamin, D ; Bertelsen, H ; Bondarenko, V ; Bychkov, V ; Callahan, J et al.
The ATLAS Inner Detector consists of three sub-systems, the pixel detector at the innermost radius, the semiconductor tracker at intermediate radii, and the transition radiation tracker (TRT) at the outermost radius in front of the electromagnetic calorimeter. The TRT provides a combination of continuous tracking with many projective measurements based on individual drift-tubes (or straws) and of electron identification based on radiator fibres or foils interleaved between the straws themselves.

ATLAS Transition Radiation Tracker test-beam results
/ Åkesson, T ; Arik, E ; Baker, K ; Baron, S ; Benjamin, D ; Bertelsen, H ; Bondarenko, V ; Bychkov, V ; Callahan, J ; Capéans-Garrido, M et al.
Several prototypes of the Transition Radiation Tracker for the ATLAS experiment at the LHC have been built and tested at the CERN SPS accelerator. Results from detailed studies of the straw-tube hit registration efficiency and drift-time measurements and of the pion and electron spectra without and with radiators are presented. [...]
