Science At JLAB

Nuclear Physics

One example of an amazing JLab discovery relates to the structure of the nucleon itself. Former SURA Board Chair Steven Wallace, himself a nuclear physicist from the University of Maryland, noted that “nucleons were once thought to be featureless, homogeneous, spinning quantum ‘balls.’ But JLab researchers have now demonstrated that nucleons are complex composite objects—a ‘whole new world’ within a quantum world. It is through the eyes of JLab researchers that we are only now beginning to understand the structure of the nucleon in the nuclear medium.”

Accelerator Physics

Illuminating collisions within the US Department of Energy’s Jefferson Lab accelerator, known as the Continuous Electron Beam Accelerator Facility (CEBAF), a stream of millions of electrons races around an underground track nearly a mile in circumference. A billion times per second, magnets steer and focus the electrons into a beam the width of a human hair

Free Electron Laser

Using superconducting radiofrequency (srf) technology, Jefferson Lab built and now operates the world’s most powerful tunable laser, known as the Jefferson Lab Free Electron Laser (FEL). The JLab FEL has been upgraded to enable output power of 14.2 kilowatts and is already being used to explore applications in science, industry and national defense.
