Large Hadron Collider restarts after three-year refit
The Large Hadron Collider (LHC), the largest and most powerful particle accelerator ever built, is ready to go back into service after a three-year overhaul and refit. On April 22, 2022 at 12:16 pm CEST, two proton beams with an injection energy of 450 GeV were sent in opposite directions around the the 27-kilometer-long (17-mile) ring.The advantage of a giant atom smasher like the LHC is that the tremendous energies it can impart on subatomic particles can cause them to strike each other so hard that they break apart in…
