Performances of the coincidence matrix ASIC of the ATLAS barrel level-1 muon trigger (original) (raw)

Abstract The ATLAS Barrel Level-1 muon trigger handles data coming from the Resistive Plate Chamber detectors, structured in three concentric layers inside the air-core barrel toroid. The trigger classifies muons within different programmable transverse momentum thresholds, and tags the identified tracks with the corresponding bunch crossing number. The algorithm looks for hit coincidences within different detector layers inside the programmed geometrical road which defines the transverse momentum cut.
