Effective selection of muon candidates is the cornerstone of the LHC physics programme. The ATLAS experiment uses a two-level trigger system for real-time selection of interesting collision events. The first-level hardware trigger system uses the Resistive Plate Chamber detector (RPC) for selecting muon candidates in the central (barrel) region of the detector. https://www.ngetikin.com/limited-buy-LA-Williams-Belial-Dragon-by-LA-Williams-Google-Pixel-2-Skin-p114135-best-save/
