Description

Electron Ion Collider (EIC) will benefit from cooling protons at the highest collision energy (γ=294). The required cooling can be provided by the Ring Electron Cooler (REC) - an RF-based non-magnetized electron cooler employing an electron storage ring. As stored electrons cool the EIC protons, their emittance is gradually increased by both the intra-beam and beam-beam scattering. To counteract the heating of electron bunches, eighteen dedicated damping wigglers are utilized. These wigglers require substantially non-linear field with peak value of 2.4 T, occupy a large portion of the electron storage ring, and dominate beam dynamics in the REC. In this paper we describe our approach to maximizing dynamic aperture in the REC, which includes careful optimization of wigglers parameters and development of an elaborate correction scheme for non-linear beam dynamics.
