A particle accelerator is a machine that generates high-energy beams of particles like electrons, protons, and ions. These particles are accelerated in a vacuum using electric and magnetic fields until they reach extremely high velocities. When these high-energy particles collide with a target, they can create new particles or study the behavior of subatomic particles. For example, the Large Hadron Collider (LHC) in Switzerland has been used to discover the Higgs Boson particle and study the properties of other particles. The discoveries made using these accelerators have advanced our understanding of the fundamental nature of matter and energy in the universe.
