RHIC Status and Plans

The Relativistic Heavy Ion Collider (RHIC) complex at Brookhaven National Laboratory has been in operation for nearly 20 years, colliding a large variety of ion species from polarized protons to uranium ions at different energies. Through a number of improvements and upgrades its luminosity performance has exceeded its design luminosity by a factor 50. This unprecedented performance makes RHIC an ideal base for a future electron-ion collider (EIC). We report the luminosity evolution and upgrade history of RHIC and present the design concept of the electron-ion collider eRHIC.
