Synchrotron radiation

Definition

Synchrotron radiation is the electromagnetic radiation emitted when charged particles, typically electrons, are accelerated radially in a magnetic field. This phenomenon occurs in synchrotrons, which are particle accelerators that produce intense beams of light spanning a wide range of wavelengths, including X-rays. The unique properties of synchrotron radiation make it an invaluable tool for a variety of scientific applications, particularly in the study of materials and molecular structures through techniques such as X-ray diffraction.
