  • Scientists use telescopes to study stars and microscopes to study living cells. At Jefferson Lab, they use CEBAF (Continuous Electron Beam Accelerator Facility) and three experimental halls to study the stuff of stars, cells and everything in between.

    At its heart, all the matter in the universe that we can see is built of particles called quarks and gluons. These particles combine to form the familiar protons and neutrons found in the nucleus of the atom.

  • 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?


    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?
