Abstract

The international linear collider (ILC) damping rings will require construction of wiggler magnets of high field quality on a large scale. We consider various designs derived from the wigglers presently in operation at the Cornell electron storage ring (CESR). Design optimization has been performed based on detailed tracking calculations of dynamic aperture and tune footprint in a full model of the damping ring. Results on finite-element modelling, transfer functions, and implications for the final engineering design will be discussed.
