After 28 years of operation, Chicago’s Fermilab in September shut down Tevatron, the world’s most powerful atom smasher. The Tevatron research program — which focused on proton-antiproton collisions — helped shape understanding of matter, energy, space and time. It also yielded breakthroughs in medical diagnostics and cancer treatment, monitoring nuclear waste and computing technology.
