Resistive Micromegas for the Muon Spectrometer Upgrade of the ATLAS Experiment

2017

It is reported on the construction and test of large scale resistive Micromegas detectors for the ATLAS New Small Wheel upgrade. The production procedure of the 2 to 3 m2 active area is described. The validation of the construction procedure is proven with results obtained with prototype detectors showing 100 µm spatial resolution in the precision coordinate and above 98% efficiency In the context of the upgrade project of the ATLAS Muon system, we report on the construction of Micromegas detectors with an active area of 2 to 3 m$^2$ . The validation of the construction procedure is proven with results obtained with prototype detectors showing 100 $\mu $m spatial resolution in the precision…
