AbstractPerformance of Electron Ion Collider (EIC) will benefit from cooling of protons at the highest collision energy (γ=294). The required cooling can be provided by the Ring Electron Cooler (REC) – a non-magnetized RF-based electron cooler, employing an electron storage ring. The REC is a “racetrack” consisting of a 170 m long cooling section (CS), a wiggler section opposing the CS and containing eighteen 2.4 T damping wigglers with highly nonlinear field profile, and two matching arcs. The REC utilizes an elaborate correction scheme to achieve the target dynamic aperture (DA) in the baseline lattice. Alignment errors in magnet placement will be present in a constructed ring and will disrupt the DA correction scheme. In this paper, we describe studies of alignment errors, their effect on the dynamic aperture, define tolerances to various misalignments and propose a procedure for misalignment correction.
