Surface commissioning of the BIS-78 sMDT chambers for the upgrade of the ATLAS muon spectrometer — •Šejla Hadžić, Oliver Kortner, Hubert Kroha, and Patrick Rieck — Max-Planck-Insitut für Physik

16 new so-called "BIS-78" sMDT chambers will be installed together with new thin-gap RPC chambers in the inner barrel layer of the ATLAS muon spectrometer in the transition region to the endcaps during the 2019/20 shutdown of the LHC in order to improve the rejection of fake muon triggers. The chambers have been constructed in 2018 and beginning of 2019. All chambers undergo extensive functionality tests with cosmic rays both before and after shipment to CERN. The noise rate and the efficiency of each drift tube are measured as well as the spatial resolution of the chamber. The presentation summarizes the results of these tests.
