Sirius, the new Brazilian Synchrotron Light Source

The use of synchrotron radiation by a great variety of fields has increased steadily worldwide. This, to a large extent, is a result of the availability of the much brighter third-generation light sources, which allowed the development of new experimental techniques. Recently, new advances in accelerator technology are opening up the possibility of even brighter sources, which are being named fourth-generation light sources. Brazil gave an important contribution to science through the development of the necessary technology and the construction of the first synchrotron in the Southern Hemisphere, the Brazilian Synchrotron Light Laboratory (LNLS), still the only one in Latin America,that operates this installation as an open facility since 1997. Its pioneering activities in synchrotron science gave rise, with time, to the Brazilian Center for Research in Energy and Materials (CNPEM), a complex of four National Laboratories – LNLS itself, the Brazilian Biosciences National Laboratory (LNBio), the Brazilian Bioethanol Science and Technology Laboratory (CTBE) and the Brazilian Nanotechnology National Laboratory (LNNano). CNPEM is a research center that benefits more than two thousand researchers yearly. Sirius, the new Brazilian synchrotron light source being constructed at CNPEM, will be one of the first fourth-generation machines in the world. It will be a 3 GeV storage ring based on a five-bend-achromat (5BA) magnetic lattice that will be able to reach 250 pm.rad emittance (bare machine). It is being planned to be a state-of-the-art light source, providing cutting edge research tools that are nonexistent today in Brazil. In this talk an overview of themain characteristics, potentialities andstatus of the project will be provided.
