Dynamics near equilibrium for intense beams in a nonlinear integrable focusing channel
Abstract
Accelerator storage ring designs based on nonlinear integrable Hamiltonian systems provide a novel testbed for studying the interplay between nonlinear dynamics and space charge at high intensity. In this work, the structure of beam Vlasov equilibria is explored for a constant focusing channel based on the nonlinear focusing potential of the Integrable Optics Test Accelerator. Finally, the dynamics of the singleparticle orbits is explored in the combined space charge and external focusing fields as a function of beam current, and the selfconsistent relaxation of a mismatched beam to equilibrium is characterized.
