Description
The New Small Wheel upgrade of the Muon Spectrometer was the largest Phase-1 upgrade project of the ATLAS detector. Two detector technologies—MicroMegas (MM) detectors and small Thin Gap Chambers (sTGCs)—were installed in the first station of the Muon Spectrometer endcap system in order to facilitate precision tracking and reduce the Level-1 trigger rate in anticipation of the increased luminosity at the High Luminosity LHC. During the current data taking period, the NSW trigger participated in the ATLAS Level-1 trigger decision, successfully providing a rate reduction of 5-7 kHz. This poster will report on the performance of the NSW trigger electronics and algorithms during data taking, as well as the associated monitoring infrastructure.
