Status of design and construction of the Transition Radiation Tracker (TRT) for the ATLAS experiment at the LHC
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 ...
متن کاملATLAS Transition Radiation Tracker test-beam results
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 drifttime measurements and of the pion and electron spectra without and with radiators are presented. r 2004 Elsevier B.V.

متن کاملATLAS Transition Radiation Tracker (TRT): Straw Tubes for Tracking and Particle Identification at the Large Hadron Collider
The ATLAS Transition Radiation Tracker (TRT) is the outermost of the three inner detector tracking subsystems and consists of ∼300000 thin-walled drift tubes (“straw tubes”) that are 4 mm in diameter. The TRT system provides ∼30 space points with ∼130 micron resolution for charged tracks with |η| < 2 and pT > 0.5 GeV/c. The TRT also provides electron identification capability by detecting trans...
متن کاملOperation of the ATLAS Transition Radiation Tracker under very high irradiation at the CERN LHC
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. The TRT performance expected at these conditions is reviewed, including pile-up effects at high lum...
متن کاملThe new ATLAS TRT read-out system
The ATLAS TRT detector [1] is very demanding in terms of electronics performance because of the high occupancy of the detector. A new version of the full read-out system, including two new ASICs and the new back-end modules, has been designed and tested successfully at 40 MHz clock rate and high trigger rate on a detector prototype. A description of this system will be given, as well as test re...
