N2 - Fully meeting the nuclear physics goals of JLEIC (Jefferson Lab Electron Ion Collider) requires a full-acceptance detector. Integration of such a detector into the collider presents many challenges for design of the beam dynamics. Small β* values at the Interaction Point (IP) needed to reach a luminosity level of a few 1033 cm-2sec-1 cause large natural chromaticities. Their compensation involves installation of dedicated chromaticity correction sections in the collider rings. Small β* values and a large space occupied by the full-acceptance detector also mean large β in the final focus area. This sets a constraint on the field quality of the magnets in the large beta areas, in order to ensure a large enough dynamic aperture. Additional complications include asymmetric lattice and beam envelopes in the Interaction Region (IR), forward detection requirements, large crossing angle with associated crab dynamics, coupling and coherent orbit distortion from the detector solenoid, etc. This paper briefly describes how we address these issues.
