Lead ion collisions. Particle tracks from the first lead ion collisions seen by the ALICE (a large ion collider experiment) detector at CERN (the European particle physics laboratory) near Geneva,Switzerland,on 7th November 2010. Each collision,produced after the ions had been accelerated to an energy of 287 TeV (tera electron volts) by the large hadron collider (LHC),leads to the production of thousands of subatomic particles. The tracks are colour-coded according to energy from low (blue) to high (red). 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. Shaded areas are elements of the detector | |
