Summarize this article for a 10 year old
Sirius is a diffraction-limited storage ring synchrotron light source at the Brazilian Synchrotron Light Laboratory (LNLS) in Campinas, São Paulo State, Brazil. It has a circumference of 518.4 metres (1,701 ft), a diameter of 165 metres (541 ft), and an electron energy of 3 GeV. The produced synchrotron radiation covers the range of infrared, optical, ultraviolet and X-ray light.[1]

Costing R$1.8 billion,[2] it was funded by the 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]
