Abstract

SLS is a high brightness light source with 4.8 nm emittance at 2.4 GeV. Particle losses due to Touschek scattering will strongly affect the beam lifetime. We present Touschek lifetime calculations based on a refined tracking procedure for determination of the lattice momentum acceptance. The dependency of lifetime on the gap height of insertion devices and on the RF cavity voltage is studied in detail for the reference optics of the SLS storage ring lattice. Including gas scattering losses we expect 3.5 hrs of total lifetime for a 1 nCb bunch charge and 0.1% coupling. Installation of a 3^rd harmonic cavity for bunch lengthening would increase the total lifetime to 8 hrs and thus is recommended
