CEBAF (Continous Electron Beam Accelerator Facility)

CEBAF (Continous Electron Beam Accelerator Facility) is the main accelerator at Jefferson Lab. Until 1996, this was the main name for the entire lab.

Layout


The CEBAF accelerator includes a polarized electron source and injector and a pair of superconducting RF linear accelerators 7/8-mile (1400 m) in length. Two arc sections with steering magnets connect these linear accelerators together. CEBAF's racetrack-shaped design is also found at other famous accelerator sites such as Stanford University's SLAC or Fermilab. The superconducting RF linear accelerators allow JLab to cool niobium to around 4 K using liquid helium, taking away electric resistance and transfers energy to an electron in the most efficient way possible. In fact, JLab has the largest liquid helium refrigerator in the world.
