Synchrotron

Definition

A synchrotron is a type of particle accelerator that uses magnetic fields to steer and accelerate charged particles, such as electrons, to nearly the speed of light in a circular path. It is distinguished by its ability to produce high-energy beams and synchrotron radiation, which is emitted when charged particles are deflected in magnetic fields. This technology plays a crucial role in various scientific fields, enabling research in materials science, biology, and medical imaging.
