Synchrotron-light – or synchrotron-radiation – sources produce very intense pulses of light/X-rays, with wave lengths and intensities that allow detailed studies of objects ranging in size from human cells, through viruses down to atoms, with a precision that  is not possible by other means. Synchrotron-light sources therefore enable a very wide range of important applied sciences, from biology and medical sciences (imaging and therapy) through pharmaceuticals, physics, chemistry and materials science to  archaeology, and can be used to improve manufacturing techniques, provide forensic evidence, and address environmental issues. The heart of a synchrotron-light source is a ring of magnets (133m in circumference in the case of SESAME) in which  electrons are stored after being accelerated to high energy. They are therefore relatively expensive devices which are frequently built by international collaborations. Working in collaboration has the important benefit that it disseminates the highest scientific and technical standards through the participating countries, which helps foster the development of a wide range of basic and applied science and industrial activities.
