  • Light travels at 186,000 miles per SECOND!

    At nearly the speed of light, CEBAF's electron beam orbits the 7/8 mile track 5 times in about 22 millionths of a second.

    How far would it go in one second?

    FAR!!

    In one second, CEBAF's electron beam would circle the earth 7 1/2 times!!

  • Jefferson Lab's electron beam will be aimed at targets like hydrogen, carbon, gold, and lead. What happens when the beam hits a target?

    Electron Beam

  • Superconductivity allows electricity to flow through a conductor without resistance. At CEBAF this is achieved by cooling the niobium cavities in the accelerator to -456oF.

    WHAT DOES THAT MEAN FOR CEBAF?

    Well, using superconducting technology, CEBAF requires an average of 20 megawatts of power to operate. That's enough power for 16,000 homes.

  • All visible matter in the universe is made from the first generation of matter particles: up quarks, down quarks and electrons.

    Quarks are very social and exist only in groups (hadrons) with other quarks.
