Abstract

The ALICE Experiment (A Large Ion Collider Experiment) aims to study the properties of quark-gluon matter using Pb-Pb collisions at a center of mass energy (per nucleon pair) of TeV with the Large Hadron Collider (LHC) at CERN. The EMCAL detector is a large area electromagnetic calorimeter. ALICE's capability to perform jet reconstruction is greatly improved by measuring the neutral energy component of jets including photons and neutral pions. The calorimeter produces also a fast, high-pT trigger providing an enhancement in high-pT events, participates in the High Level Trigger (HLT), performing online reconstruction at the full data rates and generates trigger information based on reconstructed events. The performance of prototypes has been studied in test beam measurements at FNAL and CERN and are shown. Four EMCAL super-modules have been installed at CERN and are operational. First results from data taking are presented. Moreover, an extension of EMCAL for jet-jet and γ-jet physics will be discussed.
