Collider Accelerators

Definition

Collider accelerators are complex machines designed to accelerate charged particles, such as protons or electrons, to very high energies and then collide them together. These collisions allow physicists to investigate fundamental interactions and particles at energy scales that cannot be achieved with stationary targets, leading to groundbreaking discoveries in particle physics and contributing to the historical development of the field.
