발표 초록: After close to 20 years of preparation, the dedicated heavy-ion experiment "A Large Ion Collider Experiment (ALICE)" at the CERN Large Hadron Collider (LHC) accelerator has run successfully for the last 10 years to investigate the properties of the Quark-Gluon Plasma that is the hottest and densest matter in the Universe. The matter is reproduced in the center of the ALICE by accelerating and colliding two lead ions at a few TeV in the LHC accelerator. After a short introduction into the physics of ultra-relativistic heavy-ion collisions, this talk recalls the main design choices made for the detector, the performance and important outputs of ALICE for the last 10 years. Finally, it summarizes the subject by addressing the promising outlook of heavy-ion experiment for the next 10 years that ALICE Collaboration is willing to achieve.
