Abstract:

Studies on linear and nonlinear imperfections in the SLS storage ring operated at 2.4 GeV are presented. The influence of spurious vertical dispersion and linear coupling on the vertical emittance and possible correction schemes are discussed. The deterioration of the Dynamic Aperture caused by higher order multipoles is investigated based on field calculations. Furthermore the influence of ground waves on the orbit stability is estimated.
