what is a collider
This article is about the particle accelerator. For other uses, see Collider (disambiguation). A collider is a type of particle accelerator involving directed beams of particles. Colliders may either be ring accelerators or linear accelerators, and may collide a single beam of particles against a stationary target or two beams head-on. Colliders are used as a research tool in particle physics by accelerating particles to very high kinetic energy and letting them impact other particles.
