Abstract

The tune-shifts and the beam positions resulting from kicks on horizontal or vertical corrector magnets at the SLS storage ring [1] can be qualitatively well modeled with the Tracy-2 code [2]. The code allows simulation of beam properties of the undisturbed storage ring as well as after perturbation of the system. The code can therefore be used to predict beam behavior after varying corrector magnet strengths. Unfortunately the precision of these model predictions is not very high at the moment. Once the underlying technical properties are better understood, precise predictions of beam dynamics by using the Tracy-2 code will be possible. This resembles a well understood environment opposed to the sole application of LOCO Analysis [3] which leads to precise predictions of beam dynamics without necessarily enlarging understanding of the element errors.
