particle accelerators

Subatomic collision machines

Particle accelerators are machines that use electromagnetic fields to propel charged particles—protons, electrons, ions—to extremely high speeds, often approaching the speed of light.

Scientists use them to study fundamental physics by smashing particles together and observing what emerges.

The Large Hadron Collider is the most famous example.

Smaller accelerators have practical applications in medicine and manufacturing.
