title = "Optimization of chromaticity compensation and dynamic aperture in meic collider rings",
abstract = "The conceptual design of the Medium-energy Electron- Ion Collider (MEIC) at JeffersonLab relies on an ultrasmall beta-star to achieve high luminosities of up to 1034cm-2s-1. A low-beta insertion for interaction regions unavoidablyinduces large chromatic effects that demand a proper compensation. The present approach ofchromatic compensation in the MEIC collider rings is based on a local correction schemeusing two symmetric chromatic compensation blocks that includes families of sextupoles, andare placed in a beam extension area on both sides of a collision point. It cansimultaneously compensate the first order chromaticity and chromatic beam smear at the IPwithout inducing significant second order aberrations. In this paper, we investigate boththe momentum acceptance and dynamic aperture in the MEIC ion collider ring by consideringthe aberration effects up to the third order, such as amplitude dependent tune shift. Wealso explore the compensation of the third order effects by introducing families ofoctupoles in the extended beam area.",
