Abstract: The ENC project attempts to realize an electron-nucleon collider at the upcoming Facility for Antiproton and Ion Research FAIR at GSI Darmstadt by utilizing the antiproton high-energy storage ring HESR for polarized proton and deuteron beams. The addition of a 3.3 GeV storage ring for polarized electrons will enable electron-nucleon collisions up to a center-of-mass energy of - s - 14 GeV. In such a configuration peak luminosities in the range of L = 10(32) to 10(33)cm(-')(2)s(-')(1) are feasible . Beam-beam effects in a space-charge dominated regimes in conjunction with high-energy electron cooling represents one of the main challenges for this project. In this paper beam- and spin dynamics simulations are presented, together with the required mo difications and extensions for a collision mode of the HESR storage ring and the conceptual design of this new collider complex.
