  • CEBAF THE MACHINE!

    The Continuous Electron Beam Accelerator Facility is located in a tunnel about 25 feet below ground. The oval-shaped tunnel is about 7/8 of a mile long. The tunnel is about 14 feet across and 10 feet high. Its concrete walls, floor and ceiling are about 21 inches thick. Magnets are used to direct the electron beam around the two arcs of the oval. This allows the beam to circulate up to five times before being directed into an experimental hall. With each lap around the accelerator, the beam gains additional energy.

  • The Test Lab is where Jefferson Lab designs and fabricates equipment and system critical to its research program.

    The Test Lab is where Jefferson Lab designs and fabricates equipment and system critical to its research program. It is home to the Superconducting Radiofrequency Institute, a world-leader in the superconducting radiofrequency technology used to accelerate the laboratory's electron beams. Expansion and renovation work is underway at the Test Lab. Along with a new building under construction immediately west of the Test Lab, the entire complex will be known as the Technology and Engineering Development Facility.

  • FEL

    Jefferson Lab is home to the world's most powerful tunable Free-Electron Laser.  

    Jefferson Lab is home to the world's most powerful tunable Free-Electron Laser.  The FEL uses the same superconducting radiofrequency technology as Jefferson Lab's CEBAF accelerator. The FEL has been used to conduct an extensive range of applied and basic research.Unique to the FEL is the range of light it can produce. This tunability allows scientists to test multiple wavelengths of light. Another innovation that makes Jefferson Lab's FEL unique is its use of the energy-recovery linac, which allows the FEL to recycle energy from its electrons.

  • The new experimental Hall D will use the electron beam to produce a coherent bremsstrahlung beam and house a solenoid detector to carry out a program in gluonic spectroscopy to experimentally test current understanding of quark confinement.

    The 12 GeV Upgrade is highly cost effective due to existing features of the Continuous Electron Beam Accelerator Facility (CEBAF). The superconducting radiofrequency linear accelerators contain superconducting niobium cavities operating, on average, at 50 percent above their design specifications in accelerating gradient and Q. The success of this technology opens up the possibility of a relatively simple, inexpensive upgrade of CEBAF's top energy.
