Physicist holding a piece of the lead source material used to create heavy ions for the large hadron collider (LHC) at CERN (the European particle physics laboratory) near Geneva, Switzerland. Experiments switched from proton-proton to lead ion collisions at CERN in November 2010. Lead ion collisions are expected to produce quark-gluon plasma, a primordial state of matter thought to have been present in the Universe microseconds after the Big Bang.
