40MHz Scouting Muon Studies

The 40MHz Scouting system is a novel data acquisition system, parallel to the Level-1 trigger, that collects the Level-1 trigger primitives at the full bunch crossing rate. It was first demonstrated in 2018 at the end of Run 2 and the system has been updated for Run 3. The Run 3 demonstrator captures data from multiple sources: the outputs of the Global Muon Trigger (GMT), data from Calorimeter Layer 2 and the Global Trigger (GT) and the inputs of the Barrel Muon Track Finder (BMTF).
