ALICE (A Large Ion Collider Experiment) is a detector built around the Large Hadron Collider (LHC) at CERN (the European particle physics laboratory) near Geneva, Switzerland. The LHC, the world's largest and most powerful particle collider, began operating in 2008. For ALICE, beams of ions are accelerated to collide head-on. The collision energy creates new particles that decay into other particles. These are detected by the many detector layers around the central collision point. The LHC energies have allowed study of exotic material like quark-gluon plasma, a form of quark matter. Photographed on 4th March 2019.
