electron storage ring

Also known as: electron-positron colliding beam

Quick Summary

An electron storage ring is a type of particle accelerator primarily used to create high-energy collisions between beams of particles. These rings are designed to make particles collide head-on, maximizing the available kinetic energy for interactions. This is more efficient than a stationary target, where much of the energy is lost to the motion of the particles after impact.12

Electron storage rings, often used in conjunction with positrons, are crucial for research into subatomic particles. Electrons are accelerated and then injected into the ring. Positrons are created by bombarding a target with high-energy electrons. Both types of particles then circulate in opposite directions within the same ring, guided by magnets, and collide at designated points. Detectors record the results of these annihilations.1

These rings are also powerful sources of electromagnetic radiation, particularly in the ultraviolet and X-ray regions, which are valuable for research in various scientific fields.1
