ALICE
ALICE (A Large Ion Collider Experiment) is a detector dedicated to heavy-ion physics at the Large Hadron Collider (LHC). It is designed to study the physics of strongly interacting matter at extreme energy densities, where a phase of matter called quark-gluon plasma forms. https://www.home.cern/science/experiments/alice
Via: ALICE detects the conversion of Lead into Gold at the LHC - https://www.home.cern/news/news/physics/alice-detects-conversion-lead-gold-lhc - Near-miss collisions between high-energy lead nuclei at the LHC generate intense electromagnetic fields that can knock out protons and transform lead into fleeting quantities of gold nuclei
