Description
Electron cooling at high energy requires large average current in the cooling section (CS), which can be achieved by reusing the same electron beam on many passes through the CS. One of the options to realize this cooling scheme is to use an electron storage ring. In this paper we describe a conceptual design of the Ring Electron Cooler (REC), as a potential future application for the Electron Ion Collider. The REC uses 150MeV electrons to cool protons in hadron ring while electrons themselves are being cooled by radiation damping wigglers installed in electron storage ring. Design of the REC considers electrons’ space charge, an effect of proton-electron focusing, a beam-beam scattering in the CS and electrons’ intra-beam scattering in the storage ring, as well as other collective effects. In this paper we discuss the status of the REC design and describe multiparametric optimization involved in the design efforts.
