Sirius is a
Costing
Ministry of Science, Technology, Innovation and Communications (Brazil) and the São Paulo Research Foundation.[1] Discussion started in 2008, and initial funding of R$2 million was granted in 2009. Construction started in 2015,[2] and was finished in 2018. The first electron loop around the storage ring was achieved in November 2019.[3] Its first experiments were made during COVID-19 pandemic at MANACÁ beamline, dedicated to macromolecular crystallography.[4]
Sirius is the second synchrotron lightsource constructed in Brazil. The first one, UVX, was a second generation machine operated by LNLS from 1997 to 2019.[5]
Characteristics
Sirius is used to understand the
R$
1.8 billion were invested in the project, which makes it the most ambitious scientific project ever made in Brazil.
Beamlines
Currently, Sirius has 9 operational beamlines, 1 in scientific commissioning, 2 in the assembly phase and 1 the design phase.[6]
