Sirius is one of the first 4th-generation storage rings globally and the only synchrotron in Latin America. It is currently under commissioning, with a set of 14 beamlines that will be delivered in two phases during the first years of operations and are designed to cover a wide variety of scientific programs, some of them in strategic areas for Brazil’s development.
Sirius is operated by the Brazilian Synchrotron Light Laboratory (LNLS), part of the Brazilian Center for Research in Energy and Materials (CNPEM). CNPEM is a non-profit private research and development institution under the Brazilian Ministry of Science, Technology, and Innovations (MCTI) supervision.
– Sirius currently has one operational beamline dedicated to macromolecular crystallography. The scientific commissioning of this instrument with users started in October 2020. The other five beamlines of the first phase are in the final phase of assembling or under scientific commissioning.
– From 1997 until 2019, LNLS operated UVX, the first synchrotron light source in the Southern Hemisphere. Its 1.37 GeV storage ring has delivered yearly around 3700 hours of synchrotron beam, with a reliability of about 97.5%, benefiting around 1000 researchers every year.
