3. History Edwin McMillan constructed the first electron synchrotron in 1945 The first proton synchrotron was designed by Sir Marcus Oliphant and built in 1952.

4. What is Synchrotron? Synchrotron is a particular type of cyclic particle accelerator that produces very bright light. Synchrotron light (also known as synchrotron radiation) is electromagnetic radiation that is emitted when charged particles moving at close to the speed of light are forced to change direction by a magnetic field

5. It produces not only visible light, but also infrared light, ultraviolet light and X-rays. The Light produced by synchrotrons are about 100 million times brighter than the X-rays produced by an X-ray machine in a hospital. There are more than 50 synchrotron light sources around the world.

6. How a synchrotron Works? The Canadian Light Source has 4 Components :- 1.E-Gun & Linear Accelerator. 2.Booster Ring. 3.Storage Ring. 4.Beamlines & End Stations

7. E-Gun E-gun uses 220,000 v DC power to heat up a tungsten oxide “button” which emits a small stream of electrons into a vacuum tube. These electrons are sped up in the linear accelerator to nearly the speed of light.

8. Booster Ring The beam of electrons that enters the booster ring is roughly the same thickness as a human hair. This Booster Ring is surrounded with magnets that will accelerate the power of electron stream.

9. Storage Ring The result of these manipulations is extremely brilliant light called Synchrotron Light. The Electron Circulate around the Storage Ring are passed through wigglers and undulators to release Intense electromagnetic waves.

10. Undulators wigglers

11. Beam Lines Beams of synchrotron light are filtered to select the appropriate wavelength to answer specific questions. Scientists can observe the interaction between the light and the molecules in samples. Incredible amounts of data can be recorded from these experiments.

12. Why Synchrotron? Synchrotrons produce extremely brilliant light:- providing molecular level images extensive chemical information allows advanced technology microscopes

13. Applications It Has Huge applications:- •Materials engineering(ceramic coating)

14. • Medical imaging and therapy(X-ray)

15. • Environment(pollutants in water supplies) • Forensics(forged documents) •Evaluate the performance of microchips
