“…The straws were not supported along their length and therefore particular care has to be taken during their insertion into the holes in the C-fibers rings to preserve straightness and minimize the sagitta, which is required to be less than 300 µm after completion of gluing straws into the rings. Each straw was therefore inspected after insertion, both visually and using optical tools [28] and bent straws were replaced before gluing (figure 21). Following the installation and straightness inspection of the first plane of straws, the straws in that plane were carefully glued into position without any mechanical constraints (figure 22).…”

The ATLAS TRT end-cap is a tracking drift chamber using 245,760 individual tubular drift tubes. 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 < |η| < 2.0, while the TRT barrel central η region |η| < 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.
