Abstract

To study coherent bunch instabilities for the third generation light source, ALS, it is insufficient to rely on a linear map with radiation damping for the lattice to obtain the correct dynamics. We have implemented a code for transverse bunch instabilities, using a 4-dimensional map for the lattice and wake field expansions for cavities and resistive wall effects. This model has been used to study the injection process and to determine the needed performance of the proposed feedback system for the storage ring
