Synchrotron

Definition

A synchrotron is a type of particle accelerator that produces high-energy beams of charged particles, typically electrons, by using magnetic fields to guide and synchronize their paths as they travel at speeds approaching the speed of light. This technology allows for the production of synchrotron radiation, which is a powerful source of electromagnetic radiation used in a variety of scientific applications, including materials science, biology, and medical imaging.
