The Collider Detector at Fermi National Accelerator Laboratory, home of the Tevatron. (Corbis Corporation)
- The first accelerator, built by J.D. Cockroft and E.T. Walton in 1930 at the Cavendish Laboratory of the University of Cambridge, England, accelerated protons to an energy of 300,000 electron volts (eV). At this energy, the protons have a speed of about 7,600 kilometers per second, and are traveling about 2.5% of the speed of light. The first circular accelerator, or cyclotron, was built by Ernest Lawrence with the help of M. Stanley Livingston in 1932 at the University of California in Berkeley.
- The highest energy accelerator in existence today, the Tevatron, is at the Fermi National Accelerator Laboratory, located west of Chicago. It accelerates both protons and antiprotons to an energy of about 1 trillion electron volts (TeV). At this energy, the protons and antiprotons have a speed almost as great as the speed of...
