LHC back in operation

After two years of intense maintenance and consolidation, and several months of preparation for restart, the Large Hadron Collider, the most powerful particle accelerator in the world, is back in operation.

Thanks to the work done in the last two years, it will operate at unprecedented energy - almost double that of season 1 - at 6.5 TeV per beam. With 13 TeV proton-proton collisions expected before summer, the LHC experiments will soon be exploring uncharted territory.
