It is a part of the TRT tracker which consist of the barrel and two end-caps. The TRT end-caps cover the forward and backward pseudo-rapidity region 1.0 < vertical bar eta vertical bar < 2.0, while the TRT barrel central eta region vertical bar eta vertical bar < 1.0. The TRT system provides a combination of continuous tracking with many measurements in individual drift tubes ( or straws) and of electron identification based on transition radiation from fibers or foils interleaved between the straws themselves. Along with other two sub-systems, namely the Pixel detector and Semi Conductor Tracker (SCT), the TRT constitutes the ATLAS Inner Detector. This paper describes the recently completed and installed TRT end-cap detectors, their design, assembly, integration and the acceptance tests applied during the construction.OPENParticle Tracking DetectorsLarge detector systems for particle and astroparticle physicsParticle tracking detectorsTransition radiation detectors[PHYS.HEXP]Physics [physics]/High Energy Physics - Experiment [hep-ex]500Large Detector Systems for Particle and Astroparticle PhysicsLarge detector systems for particle and astroparticle physics.Transition Radiation Detectorspublication0103 physical sciences01 natural sciencesdoi_dedup___
