Transition Radiation Tracker
Project Leader:
Daniel Froidevaux
 
Project Engineers:
Andrea Catinaccio  (mechanics)
Philippe Farthouat  (electronics)  		The outer tracker of ATLAS is a combined straw tracker and transition radiation detector. The barrel part contains 52544 axial straws of about 150 cm length at radii between 56 cm and 107 cm. The end-caps contain a total of  319488 radial straws at radii between 64 cm and 103 cm (inner end-caps), respectively 48 cm and 103 cm (outer end-caps). The TRT provides on average 36 two-dimensional measurement points with 0.170 mm resolution for charged particle tracks with |eta| < 2.5 and pT > 0.5 GeV.
