Electron Ion Collider Strong Hadron Cooling design Summary

Abstract

The Electron-Ion Collider (EIC) requires a high-energy cooler to maintain excellent beam quality and achieve high luminosity throughout long collision stores.To meet this requirement, the EIC project has adopted a novel approach known as Coherent Electron Cooling (CeC)-referred to as Strong Hadron Cooling (SHC)-which can provide rapid cooling rates at high energies.The SHC relies on an Energy Recovery Linac (ERL) to provide the intense, high-quality, and low-noise electron beam essential for the cooling process.This paper summarizes the design progress of the Strong Hadron Cooler for the EIC.We discuss key aspects of the project, including cooling physics modeling, luminosity evolution during collisions, the ERL design, risk mitigation strategies, remaining challenges, and ongoing R&D efforts.
