Synchrotron radiation

Definition

Synchrotron radiation is the electromagnetic radiation emitted when charged particles, such as electrons, are accelerated radially, typically in a synchrotron or storage ring. This radiation is produced when high-energy electrons travel close to the speed of light and are forced to change direction, resulting in the emission of photons across a wide spectrum, from infrared to X-rays. The unique properties of synchrotron radiation make it essential for various applications in research and industry, particularly in particle acceleration technologies.
