Abstract :
This article describes an automatic system to control the quality of straws installed in the wheels of the end-cap Transition Radiation Tracker of the ATLAS experiment. The system tests both the straightness and the electrical insulation of the straws during installation. The testing time per straw is 9 s; consequently it takes about 2 h to measure one layer of straws. The off-line analysis takes 20 s per straw. With this system defects can be immediately detected and corrected. This clearly influences the future performance of the detector.
