A particle accelerator is a scientific device that propels charged particles, such as electrons or protons, to high speeds and energies. These particles are then collided with each other or with target materials to study fundamental physical phenomena. Particle accelerators are essential tools in modern physics, enabling researchers to explore the building blocks of matter and the forces that govern their interactions. There are various types of particle accelerators, including linear accelerators and circular accelerators like the Large Hadron Collider. These machines have contributed to significant discoveries, such as the Higgs boson, enhancing our understanding of the universe and its origins.
