Synchrotrons are unique devices because they produce extraordinary synchrotron light (synchrotron radiation). The unique properties of this type of light include its enormous intensity; it is millions of times brighter than the light that comes to Earth from the Sun. In addition, synchrotron radiation contains electromagnetic waves from the infrared spectrum, through visible and ultraviolet light up to the X-rays. Thanks to this, scientists can study various materials in many ways, both externally and internally. In this way, they learn how these materials are built, and what their chemical composition and electrical or magnetic properties are.
