The Large Hadron Collider is up and running again

The world's most powerful particle accelerator, the Large Hadron Collider, has returned to work after a three-year hiatus for repairs and upgrades and has begun its third run. Today, beams of protons at an energy of 450 gigaelectronvolts began to circulate in the LHC ring for the first time. In the future, scientists plan to conduct experiments at collision energies of 13.6 teraelectronvolts.
