The LHC is preparing to restart at almost double the collision energy of its previous run. The new energy will allow physicists to check previously untestable theories, and explore new frontiers in particle physics. When the LHC is on, counter-rotating beams of particles will be made to collide at four interaction points 100 metres underground, around which sit the huge detectors ALICE, ATLAS, CMS and LHCb. In the video above, engineers and technicians prepare these four detectors to receive the

Exactly one year ago, the #LHC started its third physics run at the record energy of 13.6 TeV. In preparation for the new data-taking period, the four big LHC experiments underwent major upgrades, which will allow them to collect significantly larger and better data samples than in previous runs.
