Cosmic Test Stand Studies with a small-strip Thin Gap Chamber quadruplet — •Ksenia Solovieva, Jose Antonio Fernandez Pretel, Patrick Scholer, Vladislavs Plesanovs, and Ulrich Landgraf — Albert-Ludwigs University, Freiburg

The small-strip Thin Gap Chamber (sTGC) technology is being implemented in the New Small Wheel upgrade of ATLAS for improved triggering and tracking in a higher particle rate environment. The sTGC detector readout includes a pad segmentation, which plays a key role in the trigger chain. For the purpose of investigating readout and trigger parameters, a quadruplet was set up in a cosmic muon test stand in Freiburg and read out with the final ATLAS NSW readout system and the final gas mixture. Another quadruplet was also tested in the gamma irradiation facility (GIF++) at CERN with a muon beam. The results of this study will be used for comparison with the results from the local setup. This presentation discusses the goals and challenges of the dedicated setup, as well as presenting the prospective results.
