Sirius: The new Brazilian synchrotron light source


LNLS is currently engaged in the development and construction of Sirius, a new 3 GeV synchrotron light source, designed to be one of the most advanced in the world. Its ultra-low emittance (0.28 nm.rad) and high brightness will allow the execution of very competitive experiments, opening new perspectives for research in fields such as material science, structural biology, nanoscience, physics, earth and environmental science, cultural heritage, among many others. Sirius will be located inside CNPEM campus, next to the UVX current storage ring building (see the location here). For Latin America, the construction of Sirius represents a major leap into the future of synchrotron science.
