MSU NSCL East Lansing, Mich. Protons, heavy ions (1 ≤ A ≤ 238), wide range of rare isotope beams <200 A MeV Study of atomic nuclei very far from stability, nuclear matter, nuclear astrophysics, and fundamental symmetries with radioactive beams. Accelerator physics. 718 ReA3 and ReA12 facilities for gas stopping and reacceleration of radioactive beams to 3 A MeV and 12 A MeV, respectively. Recoil separators.
BNL RHIC Upton, N.Y. Heavy ion collider (d ≤ A ≤ Au) (maxima) 100 + 100 A GeV (equivalent to fixed-target collisions at 21,000 A GeV) Create, explore, and understand matter at extreme temperatures and energy densities governed by quantum chromodynamics (QCD). 1,100 Increasing RHIC’s luminosity. Detector upgrades.
Proton collider 250 + 250 GeV Analyze behavior of gluons, quarks and antiquarks in protons.
