Description: In 1971 was started the first proton-proton accelerator in the world.
Particle accelerators boost particles up to enormous energies at to speeds close to that of light, then bring them into collision. The stream of new particles born at the points of collision is recorded and analysed by detectors. Huge particle detectors measure the particles spraying out from the collision points at the LHC. Each layer of the detectors uses a different technique to track, analyse and record signals.
The curvature of particle tracks in the magnetic field allows the momentum and electric charges to be determined. Out of nearly 1000 million collisions each second, only a few have the special characteristics that might lead to new discoveries.
The LHC is filled with superconducting magnets to steer and focus the protons in bundles that repeatedly circle the ring. The totalities of protons cross 40 million times a second. Each flow of protons contains 10¹¹ protons. About one billion proton-proton collisions per second occur in the detector. Also, the colliding particles are disintegrated, forming the so-called quark-gluon plasma, which can give birth to other particles, which in turn break down, giving new.
