 While 21st century accelerators can reach energies in the trillion electron volt region, the AGS earned researchers three Nobel Prizes and today serves as the injector for Brookhaven's Relativistic Heavy Ion Collider; it remains the world's highest intensity high-energy proton accelerator.The AGS Booster, constructed in 1991, further augments the capabilities of the AGS, enabling it to accelerate more intense proton beams and heavy ions such as Gold.Brookhaven's linear particle accelerator (LINAC) provides 200 million electron volt (MeV) protons to the AGS Booster, and the Electron Beam Ion Source (EBIS) and Tandem Van de Graaff accelerators provide other ions to the AGS Booster.
