v3.2.8
The Brazilian Synchrotron Light Laboratory (LNLS) is building Sirius, a 4th generation 3 GeV storage ring based on a five bend achromat (5BA) magnetic lattice that will be able to reach 270 pm rad emittance (bare machine). The low beta straight sections of this 518 m circumference storage ring have been optimised for maximum photon brilliance (betax,y ~ 1.5 m) and to allow new configurations of insertion devices (with small BSC < 2.4 mm (v) x 4 mm (h)). Phase 1 and 2 will include 13 beamlines, 8 based on insertion devices, and 5 based on the high-brilliance 2T superbends at the center of each 5BA .The ID beamlines will cover experimental programs, such as coherent diffraction imaging of large cells, tender x-ray nano-spectroscopy, matter under extreme conditions, soft-x-ray spectroscopy of solid/liquid/gas interfaces and high energy tomography, while more conventional synchrotron techniques will make use of the 2T superbends. In this talk I will overview some of the main aspects of this new storage ring and its first beamlines, as well as the current status of the project.
