BOOSTER SYNCHROTRON FOR SIRIUS LIGHT SOURCE

A full energy 3 GeV booster for the new Brazilian Synchrotron Light Laboratory (LNLS) third generation light source, SIRIUS, is proposed. The 144 m circumference magnetic lattice consists of two super-periods of FODO cells with defocusing dipo les and focusing quadrupoles. The optics provides a low emittance beam of 38 nm.rad at 3 GeV, high horizontal betatron and zero dispersion functions at straight sections. The top-up operation requires a cycling energy ramp from 150 MeV to 3 GeV with repet ition rate of 1 Hz.
