Construction and Performance of the Precision Tracking Chambers for the ATLAS Muon Spectrometer Upgrade for High-Luminosity LHC / Kroha, Hubert (Max Planck Society (DE)) ; Buchin, Daniel (Max Planck Society (DE)) ; Voevodina, Elena (Max Planck Society (DE))
For the operation at HL-LHC, the MDT chambers of the inner barrel layer (BIS) of the ATLAS muon spectrometer will be replaced by small-diameter Muon Drift Tube (sMDT) chambers which will be integrated with triplets of thin-gap RPC chambers in order to improve the acceptance and robustness of the barrel muon trigger system. [...]
