Online optimization of storage ring nonlinear beam dynamics

Online optimization of storage ring nonlinear beam dynamics

We propose to optimize the nonlinear beam dynamics of existing and future storage rings with direct online optimization techniques. This approach may have crucial importance for the implementation of diffraction limited storage rings. In this paper considerations and algorithms for the online optimi...
