| Abstract | The QCD theory (Quantum ChromoDynamics) predicts the presence of a new phase of the nuclear matter at very high temperature. This phase, characterized by a deconfinement of quarks within hadrons, is called QGP (Quark Gluon Plasma). The muon spectrometer of the ALICE experiment (A Large Ion Collider Experiment) aims at investigating the propertiesof the QGP at the extreme energy density reached in heavy ion collisions at LHC (Large Hadron Collider). The trigger system of the Muon Spectrometer, called MUON TRG mainly come under the responsability of the Clermont-Ferrand ALICE team. It consists of four planes of RPC (Resistive Plate Chamber) detectors with a total area of 140 m2 , 21k front-end channels and fast-decision electronics. It is designed to reconstruct (muon) tracks online, in a large background environment. A fast trigger decision, for both single-muons and dimuons, is delivered each 25 ns (40 MHz) with a latency with respect to the interaction of about 800 ns. The performances, especially the ones related to trigger decision, obtained with dedicated test tools, cosmic rays, first LHC injection beams and first proton-proton collisions at √s = 900 GeV will be presented. |
