SCT and TRT Performance from Cosmic Ray Runs

The ATLAS SCT and TRT detectors have been integrated into one barrel and two end-cap parts. Cosmic ray runs of the combined detectors are used to study the individual and combined detector integration and performance. This has taken place both in the surface building (SR1) and after installation in the ATLAS cavern. This article focuses on the most resent results, which includes timing in and synchronisation procedures, noise studies as well as initial efficiency, tracking and alignment results
