A study of the tracking performance of irradiated SCT prototypes using test beam data 003

In beam tests of SCT module prototypes, tracking efficiency and noise occupancy per detector plane are routinely measured. ATLAS simulations, on the other hand, predict the efficiency and fake rates for the complete inner detector in a realistic environment. In the H8 test beam in August 2002 an attempt was made to bridge the gap between simulation and measurement. To this end tracks were reconstructed using only the information from an array of prototype SCT modules. In this note the most important results are presented.
