Swiss Light Source
The Swiss Light Source (SLS) at the Paul Scherrer Institut houses a machine called a synchrotron that produces extremely bright light for scientific research. In designing the SLS, a high priority was given to quality (high brightness), flexibility (wide wavelength spectrum) and stability (very stable temperature conditions) of the primary electron beam and the secondary photon beams. It acts both as a giant microscope and as a multi-coloured micro-spotlight. It allows researchers from industry and academia to delve into previously unexplored reaches of science: for example, it can be used to decode the structure of proteins or to investigate the characteristics of superconductors – and all this happens at sizes down to one millionth of a millimetre!

With an energy of 2.4 GeV, it provides photon beams of high brightness for research in materials science, biology and chemistry.
