Development of gas and high voltage systems for a small-strip Thin Gap Chamber quadruplet — •José Antonio Fernández Pretel, Ksenia Solovieva, Bernhard Pfeifer, Jürgen Tobias, Patrick Scholer, Ulrich Landgraf, and Vladislavs Plesanovs — Albert-Ludwigs Universität Freiburg

In the ATLAS detector, a good performance of the trigger and tracking systems is needed to ensure its physics program. For this purpose, the end-cap muon system has been upgraded by installing the so-called New Small Wheel. The small-strip Thin Gap Chambers (or sTGCs for short, one of its main technologies) are multi-wire proportional counters running with a working mixture of CO₂:n-pentane (55:45) and a high voltage about 3kV for signal amplification. For the test setup being designed in Freiburg, a gas and high voltage systems are needed to run sTGCs, whose optimal operation needs to be guaranteed in real time via monitoring. In this presentation, the mixing, delivery and storage components of the gas system, the high-voltage and monitoring systems to run sTGCs in Freiburg are discussed.
