Quarks are difficult to study, because the force that binds quarks together (through the exchange of gluons) is so strong that we observe them only when they are combined into larger, composite particles, such as protons and neutrons. So if we wanted to measure the size of these smallest building blocks of matter, how would we do it?

The lab gives scientists a unique and unprecedented probe to study quarks, the particles that make up protons and neutrons in the atom's nucleus. The accelerator delivers a continuous beam to a target, like hydrogen, carbon, gold or lead. When the beam collides with its target, particles scatter. By studying the speed, direction and energy of the scattered particles scientists will learn more about how the nucleus is put together.

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.

Effective January 1, 2004, all applicants for a driver's license or photo ID card must show proof of U.S. Citizenship or Legal Presence in the United States. A U.S. birth certificate or unexpired U.S. passport will serve as both proof of identity and proof of legal presence. It can also be proved using a variety of other documents, such as a Certificate of Citizenship, Resident Alien Card or a valid foreign passport with a visa, I-94 or I-94W from a participating country.
