A cooling storage ring for an electron-ion collider

Electron cooling is a two-species process for lowering the emittance of a beam of particles, providing a powerful pathway to higher luminosity in colliding beams. A first design of a 6 GeV/u storage ring for cooling ions as an augmentation to the Medium Energy Ion Collider (MEIC) is presented, along with some remarks on the particulars of electron cooling in this ring.
