Study of the Position Resolution of Large Scale Micromegas Detectors — •Vladislavs Plesanovs, Patrick Scholer, Ulrich Landgraf, and Gregor Herten — University of Freiburg

During the current Long Shutdown 2 (LS2), the ATLAS muon spectrometer will receive an upgrade with the New Small Wheels (NSW), which consist of two new technologies, the sTGC detector (trigger) and the Micromegas detector (tracking).

The performance parameters of the Micromegas detectors, such as efficiency, gain, and position resolution, have been studied in the past with cosmic muons and test beams. In a recent study using cosmic muons, which forms the basis for this presentation, an attempt was made to improve the position resolution using a charge-weighted mean time correction.
