Accelerates particles to high energies.

At the heart of the Large Hadron Collider (LHC) lies its remarkable ability to accelerate particles to incredibly high energies. This acceleration process plays a crucial role in unlocking the secrets of the universe.

The LHC accelerates protons, the nuclei of hydrogen atoms, to energies of 13 teraelectronvolts (TeV). This energy is about a trillion times higher than the energy of protons in sunlight. To achieve this, the LHC uses a series of powerful superconducting magnets, which guide and focus the proton beams as they circulate through the accelerator ring.

As the protons whiz around the LHC, they gain energy from radio frequency cavities. These cavities act like tiny particle accelerators, giving the protons a boost in energy each time they pass through. The protons make millions of laps around the LHC, gaining energy with each lap until they reach their target energy.

Once the protons reach the desired energy, they are directed into collision points, where they smash into each other head-on. These collisions recreate the conditions that existed shortly after the Big Bang, the moment when the universe began. By studying the products of these collisions, scientists can gain insights into the fundamental laws of nature and the origin of the universe.

Accelerating particles to high energies allows scientists to probe the deepest mysteries of the universe, such as the nature of dark matter, the existence of extra dimensions, and the unification of the fundamental forces. The LHC's ability to reach unprecedented energies opens up new frontiers in our understanding of the cosmos.
