| Abstract |
Sirius is a 3 GeV synchrotron light source that is being built by the Brazilian Synchrotron Light Laboratory (LNLS). The electron storage ring uses the multi-bend-achromat approach (5BA in this case) to achieve a very low beam emittance of 0.28 nm.rad. The 518 m circumference contains 20 straight sections of alternating 6 and 7 meters in length, to be used for insertion devices as well as injection and RF systems. The 5BA cell is modified to accommodate a thin high field dipole (for 1.4˚ deflection) in the center of the middle bend producing hard X-ray radiation (12 keV critical energy) with a modest contribution to the total energy loss. This high field dipole (2.0 T) will be made of permanent magnet material, whereas the low field (0.58 T) ones, responsible for the main beam deflection, will be electromagnetic. Many challenges are associated with this kind of lattice, including both in beam dynamics and in accelerator engineering, that require R&D on new techniques. In this paper we discuss the main issues and achievements for Sirius during the last year.
