What is a Light Source (http://www.lightsources.org/) Accelerators producing intense beams of X-rays, ultra-violet and infrared light, making possible both basic and applied research in fields ranging from physics to biology and technology, which are not possible with more conventional equipment. Light refers to visible light, but also includes light with wavelengths that we cannot see, such as: radio waves, microwaves, infrared, ultraviolet, X-rays, and gamma rays. Alvaro R. De Pierro, University of S˜ ao Paulo, Department of Applied Mathematics and Statistics, Brazil Tomography with Synchrotron Radiation
What is a Light Source As a general rule, ◮ short-wavelength (hard) X-rays are most useful for probing atomic structure Alvaro R. De Pierro, University of S˜ ao Paulo, Department of Applied Mathematics and Statistics, Brazil Tomography with Synchrotron Radiation

The Ring Electron gun (1-2). Electrons enter a circular-shaped booster ring (3), accelerated to relativistic speeds. Finally ,they enter another ring, a storage ring (4), where they circulate for hours. Special bending magnets help them keep to their circular path. Synchrotron light is produced when the electrons change direction around the ring when manipulated by bending magnets (5), entering beamlines (gates) (6). Alvaro R.
