Engineers sent a 400-amp electrical current through the fragment of metal that was isolated as the problem. Once the fragment melted, the short circuit that caused the “indefinite” delay disappeared.
The reactivation of the world’s largest atom-smasher was postponed after engineers noted issues with the 17-mile-round collider’s magnets.
The LHC, the world’s largest and most powerful particle accelerator, led scientists to find the theoretical Higgs Boson particle, an elementary particle in the Standard Model of particle physics, earning CERN engineers a Nobel Prize in Physics in 2013.
