The Electron Ion Collider (EIC) will be a next-generation facility for the study of the strong interaction (QCD). JLab’s MEIC is designed for high luminosities of up to 1034 cm-2 s-1. This is achieved in part due to an aggressively small beta-star, which imposes stringent requirements on the collider rings’ dynamical properties. Additionally, one of the unique features of MEIC is a full-acceptance detector with a dedicated, small-angle, high-resolution detection system, capable of covering a wide range of momenta (and charge-to-mass ratios) with respect to the original ion beam to enable access to new physics. We present an interaction region design developed with close integration of the detection and beam dynamical aspects. The dynamical aspect of the design rests on a symmetry-based concept for compensation of non-linear effects. The optics and geometry have been optimized to accommodate the detection requirements and to ensure the interaction region’s modularity for easiness of integration into the collider ring lattices. As a result, the design offers an excellent detector performance combined with the necessary non-linear dynamical properties.
