Challenging luminosity measurements at the Electron-Ion Collider

A precise determination of absolute luminosity, using the bremsstrahlung process, at future Electron-Ion Collider (EIC) will be very demanding, and its three major challenges are discussed herein. First, rate suppression due to so-called beam size effect has well controlled. Secondly, impact huge synchrotron radiation fluxes should mitigated. Thirdly, enormous event rates, in excess 10 GHz, have coped with. basic layout luminosity measurement setup EIC, addressing these issues, is proposed, including preliminary detector technology choices. Finally, uncertainties proposed methods also discussed.
